How NexPCB Keeps Stock Reliable
NexPCB works with 3 major distributors (Arrow, Digi-Key, Mouser) to reorder modules when levels dip below 20% of average monthly demand. For example, if ESP32-WROOM-32E stock falls to 440 units (20% of 2,200), a reorder triggers immediately, with new stock arriving in 7-10 days. This system cut “out-of-stock” incidents by 75%in 2023 compared to 2021.
Real-World Impact
Customers using NexPCB’s stocked modules see tangible benefits. A 2023 survey found:
-
78% of users finished prototypes 2 weeks earlier than planned
-
62% reduced BOM costs by avoiding premium “expedited shipping” fees
-
90% of emergency orders (needing <48-hour delivery) were fulfilled as requested
Take a recent case: A startup building a smart thermostat needed 500 ESP32 modules fast. With NexPCB’s stock, they skipped a 3-week wait for overseas suppliers.
Popular Stocked Module Examples
NexPCB’s most requested stocked modules tackle everyday project hurdles—grab the ESP32-WROOM-32E Wi-Fi/BT combo (2,200+ units on hand) for IoT builds, TI’s TPS5430 buck converter (600+ units) for power designs, or SIM800C GSM modules (800+ units) for trackers. These parts cover 65% of customer projects, with 92% shipping same-week.
Take the ESP32-WROOM-32E first: it’s a go-to for smart home gadgets and wearables because it packs Wi-Fi 4, BT 5.0, and 520KB of SRAM. Engineers love it for prototyping: a 2023 survey found 7 out of 10 IoT developers use this exact module, and NexPCB’s stock cuts their wait time from 3 weeks (overseas suppliers) to 2 days. Monthly demand is 1,500 units, and NexPCB reorders from Arrow when stock dips below 440 units (20% of average use).
Then there’s TI’s TPS5430 buck converter: It takes 60V input and spits out 3A at 5V with 95% efficiency—meaning less heat (40% less than cheaper alternatives) and no bulky heatsinks. For a client building industrial LED strips, this saved them $1.20 per uniton heatsinks and cut assembly time by 20 minutes per board. NexPCB has 600+ in stock, and since monthly demand hits 900 units, they partner with Digi-Key to keep replenishment cycles tight (7-10 days from order to arrival).
Don’t overlook the SIM800C GSM/GPRS module—it’s in 65% of NexPCB’s IoT tracker projects. Quad-band support (works globally) and a -40°C to +85°C temperature range make it perfect for outdoor gear like logistics trackers. A startup making fleet monitors used 300 SIM800Cs from NexPCB’s stock: they finished their MVP 3 weeks early, secured seed funding, and now ship 500 units/month. The module’s 18 for newer LTE versions) also helps clients keep BOM costs low.
For sensor lovers, the BMP280 barometric pressure sensor is a staple. It measures 0-10 bar with I2C/SPI interfaces. NexPCB has 900+ in stock, and monthly demand is 600 units. One weather station maker said using the BMP280 (instead of a discrete pressure sensor) cut their prototype’s size by 30% and improved accuracy by 15%.
To make this tangible, here’s a snapshot of NexPCB’s top-stocked modules (as of July 2024):

Stock Levels for Common Modules
NexPCB maintains consistent, data-driven stock levels for common modules, with 5,000+ units across 12 high-demand types—including 2,200+ ESP32-WROOM-32E Wi-Fi combos, 600+ TI TPS5430 buck converters, and 800+ SIM800C GSM modules. They restock 80% of inventory weeklyand hit 95% same-week fulfillment, cutting project delays caused by part shortages.
It’s tied to 5+ years of customer purchase data. he ESP32-WROOM-32E sees 1,500 monthly orderson average. When stock dips below 440 units (20% of that monthly demand), NexPCB auto-reorders from Arrow, with new stock arriving in 7-10 days. This system slash “out-of-stock” incidents by 75% from 2021 to 2023.
Take the TI TPS5430 buck converter next: 900 monthly orders drive NexPCB to keep 600+ units on hand. It’s a top pick for motor drivers and LED supplies, with 95% efficiency (40% better than cheaper alternatives). A client building industrial LED strips told us: “Having this in stock meant we avoided $1.20/unit heatsink costs and shaved 20 minutes off assembly.”
SIM800C GSM modules are another staple, with 700 monthly orders and 800+ units stocked. Its quad-band support (-40°C to +85°C range) makes it critical for logistics trackers. A startup using 300 SIM800Cs from NexPCB’s stock finished their MVP 3 weeks early. The 18 for LTE versions) also keeps BOMs lean.
The BMP280 barometric sensor, for instance, has 900+ units in stock and sees 600 monthly orders. one maker said it cut prototype size by 30% and boosted accuracy by 15%. Even niche parts like the HC-SR04 ultrasonic sensor (1,500+ units, 1,200 monthly orders) stay stocked.
To keep levels precise, NexPCB uses a 20% threshold rule: if any module’s stock drops below 20% of its 3-month average demand, a reorder triggers immediately. This isn’t guesswork—data from 2022 showed that missing this threshold caused 60% of past shortages.
Fast Access to Stocked Modules
Getting stocked modules from NexPCB is fast and frictionless—engineers use their real-time inventory tool to find parts in <2 minutes, and 92% of orders ship same-week. For example, a smart thermostat startup ordered 500 ESP32-WROOM-32E modules and got them in 24 hours, avoiding the 3-week delay they’d face with overseas suppliers.
At the core of this speed is NexPCB’s real-time module inventory portal, updated every 15 minutes. A 2023 user survey found 88% of engineers finalize BOMs in <2 minutes using this tool, down from 15 minutes when relying on manual confirmations.
Behind the scenes, NexPCB’s picking process is streamlined: stocked modules go from warehouse shelves to packing stations in under 1 hour. For items with live stock, 92% ship via DHL or FedEx same-week, with domestic orders hitting doorsteps in 24-48 hours. Last quarter, a logistics tracker client needed 300 SIM800C GSM modules—they ordered at 2 PM local time and got a shipping confirmation by 3 PM.
NexPCB reorders modules when stock dips below 20% of their 3-month average demand. Take the ESP32-WROOM-32E: with 1,500 monthly orders, they keep 2,200+ units on hand. If stock falls to 440 (20%). For less frequent but critical parts like the HC-SR04 ultrasonic sensor (1,200 monthly orders, 1,500+ stocked), they use the same rule: restock before you run out.
A wearable startup testing a new fitness tracker needed 200 BMP 280 pressure sensors. They checked NexPCB’s portal at 10 AM, saw 900+ in stock. That saved them 12 hours of work and let them launch their MVP a month earlier.
A medical device client realized they needed 50 extra TPS5430 buck converters for regulatory testing. They logged into NexPCB’s portal at 4 PM—still 200 units in stock—and got them shipped by 6 PM. The converters arrived at 9 AM the next day. This shaved $15,000 off their certification costs .
How to Check NexPCB’s Module Stock
Checking NexPCB’s module stock is quick and transparent, updated every 15 minutes. Last month, 92% of users found parts in <3 clicks, avoiding the 3-week delays of overseas suppliers.
For example, filtering “Wi-Fi/BT combos” pulls up 8 active modules, each showing live stock counts(like 2,200+ ESP32-WROOM-32Es) and “estimated restock date” if low—say, 7-10 days for a module dipping below 20% demand.
Dig deeper: each module listing includes specs (e.g., “ESP32-WROOM-32E: Wi-Fi 4, BT 5.0, 520KB SRAM”) and monthly demand data. A 2023 user survey found engineers using this data reduced “wrong part” orders by 35%.
NexPCB emails or texts when stock hits your target—like if you want 500 SIM 800Cs, set a 500-unit alert. 75% of users who set alerts got parts within 5 days of restocking, avoiding project holds.
A robotics team testing a new drone used this: they saw 1,500+ HC-SR04 ultrasonic sensors in stock (yellow status, meaning 20% below monthly demand) and reordered immediately—securing 200 units before the next restock.
If the TPS5430 buck converter hits 440 units (20% of monthly demand), the tool notes “restock in 7-10 days from Arrow.” This lets you decide: wait 10 days or source elsewhere with a premium. A startup building LED drivers chose to wait—saving $800vs.
To make this even clearer, here’s a snapshot of what you’ll see on NexPCB’s stock portal (based on July 2024 data):
