CT, USA · SMALL-BATCH ELECTRONICS
Meridian Electronics builds developer modules and kits for the ICs that power modern hardware. From ADCs to flash memory, oscillators, USB modules, and more. Clean layouts, real documentation and top-of-the-line chips ensure quality results. No unlabeled boards. No mystery pinouts.
WHY WE BUILD
We understand the challenges that come from cheap knockoff chips, unlabeled breakout boards, and modules with zero documentation. We want to get rid of all of that — with high quality, easy to understand, documented, tested, impeccable products. Why should an inventor spend days, even weeks, figuring out how to build a USB-C host, when we can do that for them? Built by hobbyists, for hobbyists.

CURRENT LINEUP
Every module ships with pinouts, example code, and notes on how to actually use it — not just a chip glued to a PCB.
This USB-C Breakout Module features pin headers for VDD (pin 1 & 6), GND (pin 2 & 5), and the differential data pairs (D- pin 3, D+ pin 4). The module is hard wired with 5.1k CC resistors, configuring it as a 5v slave. The module features comprehensive ESD protections, including diodes on VBUS and data pairs, a polyfuse and a 10uF capacitor.
This USB-B Breakout Module features pin headers for VDD (pin 4), GND (pin 1 & 5), and the differential data pairs (D- pin 2, D+ pin 3). The module includes a AP2171W power switch, configuring it as a 5v host. The module features comprehensive ESD protections, including diodes on VBUS and data pairs, a 10uF capacitor, and the power switch.
This DAC Breakout Module breaks out GND (pin 1), VDD (pin 5), I2C (SCL & SDA on pins 2 and pin 3 respectfully) & output voltage (pin 4). This board features the 12 bit MCP4725 series typically operating on 3.3v or 5v. This module features 1uF & 100nF capacitors on VDD, and an LED indicating good power.
This ATMEGA328 Developer Kit & Datasheet has everything you need to build your very own MCU on a breadboard/protoboard. This kit contains one ATMEGA328P, capacitors, resistors, leds, LDO voltage regulator, ESD protections, memory, a programmable timer, switches & optionally an rp2040 for seamless UART programming. If you choose to include the RP2040 as the programmer, you get built-in USB-C > UART programming and a serial monitor for all your debugging needs. You may also opt for the classic USB to serial adapter, featuring chips such as the CH340.
DOCUMENTATION
Pinouts, example code, and debugging notes — not a stock photo and a shrug.
WHO WE ARE
Meridian Electronics is a small electronics company based out of Connecticut. We design and build developer modules and kits for the chips that power modern hardware — the parts every project needs but nobody wants to spend a weekend figuring out. Every board we ship is designed for quality: clean layouts, real documentation, and top-of-the-line chips.
We're built for hobbyists and innovators alike, and we take custom orders — in fact, we encourage them. If you're working on something and need a board that doesn't exist yet, that's exactly the kind of tedious problem we like solving.
SHOP POLICIES
