About the XIAO LCD PCB

XIAO LCD is an open source PCB design by bitbank2, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 40.1 × 31.7 mm, with 7 components from 5 distinct parts.

Other key parts include the SeeeduinoXIAO. By type, the board carries 2 connectors, 2 switches, 2 resistors and 1 IC.

It belongs with the displays & leds and dev boards & breakouts designs in this gallery.

From the project

A place to share all of my PCB projects

A collection of KiCad PCB projects. I've included the Gerber files (zipped) so that you can directly order these PCBs from your favorite PCB supplier without having to use KiCad.

A DS3231 realtime clock breakout board modelled after the RPI RTC boards. The 5 pin header matches the pinout of the Raspberry Pi and adds the interrupt pin (pulled up to 3.3v). It includes a QWIIC connector (JST 4-pin 1mm) and I also added a small switch to completely disconnect the backup battery if you plan on leaving it unused for an extended period of time. There's a small CR44 backup battery soldered to the…
