Kicad design files for prism laser direct imager using up5k FPGA and ESP32
An ESP32 controlled thermal printer solution to print payment receipts as payments are made to the LNbits TPoS extension.
This dual-MCU repository features a heterogeneous architecture pairing an ESP32-P4 application processor with an ESP32-C5 Wi-Fi 6/BLE hub. Linked over a high-bandwidth 4-bit parallel SDIO interconnect, this design decouples heavy multimedia task execution from the networking stack to completely eliminate application interrupt starvation.
Open Muscle Dev Kit (V0/V1): ESP32-C3 sensor-cell hardware (KiCad PCBs + gerbers) and MicroPython firmware for the OpenMuscle pressure-sensing platform.
Small RGB LED Pendant using 1010 (1.0x1.0mm) WS2812B LEDs powered by an ESP32-C3 Mini with a BNO055 IMU
