CT, USA · SMALL-BATCH ELECTRONICS
Meridian Electronic 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. No inventor spend days or even weeks figuring out how to build a USB-C host, 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. Every Kit comes with guides, code, programming information and more. Zero guesswork, quality products.
This USB-C Breakout Module features pin headers for VDD, GND, and the differential data pairs. The module is hard wired with 5.1k CC resistors, configuring it as a 5v sink (This module receives 5v, it's used to power your board). The module features comprehensive ESD & current protections, including diodes on VBUS and data pairs, a polyfuse and a 10uF capacitor.
This USB-A Breakout Module features pin headers for VDD, GND, and the differential data pairs. The module is a USB-A receptacle with +5v VBUS and host-side hardware (this USB module provides power from your board, to the peripheral). The module features an AP2171W power switch for USB VBUS. The module features comprehensive ESD & overcurrent protections, including diodes on data pairs along with decoupling capacitors & the power switch.
This Micro USB-B Breakout Module features pin headers for VDD, GND, and the differential data pairs. The module features an AP2171W power switch for USB VBUS. The module features comprehensive ESD and current protections, including diodes on VBUS and data pairs, along with decoupling capacitors & the power switch. This USB-B is configured as a Host, which means your board provides the USB-B female port with power, to supply external peripherals.
The MCP4725 is a 12 bit digital to analog converter (DAC) with integrated EEPROM. This board breaks out GND, VDD, SDA, SCL & VOUT (output). The operating voltage of the DAC is 2.7-5.5v and typically has a 6 micro second settling time. This module features 1uF & 100nF capacitors on VDD, and an LED indicating good power. The A0 address pin is tied to GND by default, giving it a 0x60 I2C address.
The Meridian MIC1555 breakout brings a compact CMOS timer onto five 0.1-inch-spaced header connections, making it easier to build timing circuits on a breadboard without working directly with the tiny SOT-23 package. The board includes 100 nF and 10 µF supply-decoupling capacitors and a power indicator LED. The external timing resistor and capacitor are not included; add these using the example circuit or your own calculated values.
This board features an MCP4661T, which is a 100 kΩ (±20%), 8-bit/257 step, Dual-Circuit Digital Potentiometer. The board operating voltage is 2.7v-5.5v, and features pin headers for I2C, ground, power, and analog terminals. This board can also act as a programmable voltage divider, using the terminals as a voltage range, and W (access) as the voltage output. This board features an LED for power, a 10uF ceramic and 100nF ceramic capacitors, along with 4.7k pull up resistors for SCL and SDA. (All address pins are tied to ground).
This ATMEGA328 Breadboard kit allows you to build out your very own MCU on a breadboard/protoboard. The ATMEGA328 is the chip used on the famous Arduino Uno, and it features 32KB of Flash and 2KB SRAM. The chip runs on 1.8-5.5v and can reach a top frequency of 20MHz (at 4.5v+). Native programming is available via SPI, however the preinstalled bootloader allows uploading sketches over UART.
This ATMEGA4809 Breadboard kit allows you to build out your very own MCU on a breadboard/protoboard. The ATMEGA4809 includes 48KB of Flash and 6KB SRAM. The chip runs from 1.8-5.5v and can reach a top frequency of 20MHz (voltage dependent). The ATMEGA4809 is a part of the newer megaAVR 0-series. Programming is available via UPDI, which is a single line serial connection. If you use the USB-UART programmer, by connecting RX to UPDI pin, and TX to UPDI through a 4.7kΩ series resistor, it functions as a USB-UPDI programmer.
DOCUMENTATION
Pinouts, example code, and debugging notes — not a stock photo and a shrug.
WHO WE ARE
Meridian Electronic is a small electronic 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
