Explorer Shield

by Unexpected Maker

The Explorer Shield was designed to be a multi-purpose board that can be used for all sorts of activities like prototyping output, experimentation, and even games.

It has lots of goodies on it, including:

  • 240x240 RGB LCD display
  • 12 Capacitive touch buttons
  • Micro SD card slot
  • 3-axis accelerometer
  • Light sensor
  • Mono audio
  • Reset button
  • STEMMA/QWIIC connector
  • LiPo connector plus power switch
  • Headers for your TinyPICO or TinyS2 with all pins broken out in a second row

Some of the GPIO that are used for things like the IMU Interrupt and SD Card detect etc have solder jumper pads that can be cut if you don’t need that functionality, and would like to use that IO for something else.


If you power the Explorer Shield and TinyPICO/TinyS2 from the shield JST connector, you can use the slide switch on the shield to power down everything. Make sure you have the switch turned on, if you want to charge the battery when the USB cable is plugged in.


Developing demo projects and libraries specific for the Explorer shield is an ongoing project. The aim is to have Arduino, MicroPython and CircuitPython (TinyS2) projects available over time, but all platforms have libraries that support all of the features of the Explorer shield currently available, so you can hit the ground running with full peripheral support right away.
