Building a GPS Speedometer with RP2040-Zero
Iturriaga Jul 11,2025
Build a Feature-Packed GPS Speedometer with an RP2040This project guide will walk you through building a multi-function GPS speedometer and trip computer using an RP2040 microcontroller. It leverages a GPS module for real-time data and presents it on a color display through a clean, multi-page interface.Instead of a simple speed readout, this device provides five distinct data screens you can cycle through with a rotary encoder. It’s a practical tool for anyone who wants detailed metrics on thei...

ESP32 Breakout with on board I2S DAC, Micro SD socket, and 3.3v to 5v level shifters
Reboot Jul 11,2025
This breakout board has female headers for a 30 pin ESP32 DOIT Dev module (provided by the user of the pcb)It has an on board stereo PT8211 I2S DAC, 3.5mm audio jack (low level, can be recorded directly or amplified for playback),and a Micro SD card socket.This allows the board to be used to easily access SD cards and play back audio.There is also a 2x10 header that allows interfacing with the ESP32 through on board level shifters.This allows interfacing with 5V logic projects that use I2C, SPI,...

ESP01 board
? Jun 28,2025
Hello PCBWayers!You probably know that ESP01S/01 boards can be a little difficult to use in an easier way, and they don't fit classic breadboards. Over time, I've made a few adapter circuits, first for the breadboard; then a programming circuit using the FTD232RL, and step 3 was to build a circuit that would allow me to use the module at 5V.I recently designed a PCB according to my needs, aesthetically more beautiful and more practical then the older version. It's a small, simple and effective P...

Snake Game Console MAX
Arnov sharma Jun 27,2025
Hey everyone! Presenting the Snake Game Console MAXThe updated Snake Game Console incorporates two RGB 64x32 P3 matrix panels into a single ultrawide 128x32 display. It uses the same PICO 2 display driver as the previous project, but I designed a new 3D-printed frame to accommodate both displays adequately, complete with integrated handgrips and a D-pad buttons PCB for snake control.We developed the original Snake game by reusing and tweaking code from the previous Snake Game project. The g...

DIY STM32 Alarm Clock with 7-Segment Display (Using Arduino IDE)
Pavleski Jun 26,2025
 This time I will present you a classic 7 segment display alarm clock which will represent another one from my series of DIY unusual and ordinary clocks which you can watch on my playlist. In this case, it is characteristic that is used the STM32 microcontroller board known as "Blue Pill". It is a popular and inexpensive development board based on the STM32F103C8T6 microcontroller from STMicroelectronics. The ARM Cortex-M3 core offers much more processing power and peripherals compared...

8x TCA9555 SHIELD (+128 pins for Arduino)
YT Jun 25,2025
This pcb it's made for people who need tons of pins. In fact this shield adds 128 pins to your Arduino. It works using I2C and you can then communicate with the 8 TCA9555. The pullup resistors for the I2C lines are already included in the PCB so you don't have to use external ones
