CS4344
sneakylizard123-4/CS4344
The CS4344 is a 24-bit stereo DAC that accepts I2S audio and runs from a single 3.3 V supply. This board gives it a 6-pin 2.54 mm header, a 3.5 mm stereo jack, and the passives it needs. There is no configuration bus.

ESP32-S3 Module
sneakylizard123-4/ESP32-S3_Module
This is a small, self-contained development board built around the ESP32-S3-WROOM-1U. The idea is a go-to prototyping board: drop in a LiPo, plug in USB-C, and you have a programmable ESP32-S3 with WiFi/BLE/Zigbee, a…

FPGA Board
sneakylizard123-4/FPGA_Board
It is built around the Lattice iCE40 FPGA, designed to be programmed over USB through the on-board FT232H. The SPI flash boots the bitstream on power-up.

Mega2560plus
sneakylizard123-4/Mega2560plus
Mega 2560+ is an upgraded version of the Arduino Mega 2560. It keeps the same form factor and pinout as the original so it still works with every Mega shield, but it adds an onboard sensor suite and an ESP32-S3…

MP3player
sneakylizard123-4/MP3player
Why the STM32H743: it has the RAM to buffer audio enough peripherals that almost every feature ended up on its own bus and 480MHz means I never have to care about optimization.

NRF24
sneakylizard123-4/nRF24
A small 2.4GHz module based on the nRF24L01P+, with an SMA jack for an external antenna, an on-board RFX2401C PA/LNA for extra range, and a breadboard friendly SPI header. Runs from 3.3V or 5V off an on-board LDO.
