Description

A Minibadge that can hold and power the Seeed XIAO ESP32 modules. It features 1206 diodes to prevent the XIAO from backfeeding power to the main badge, should you plug USB in at the same time. The Minibadge has solderable jumper pads to connect 3.3v, 5v, SDA, and SCL to your ESP. This is untested, and will be updated, but I recommend just soldering the 3.3V pad. I would like to see if it's at all possible for the badge next year to work with this badge over I2C.

Supports:

• XIAO ESP32-S3 + Wio-SX1262 (Meshtastic)
• XIAO ESP32-C6 (Thread/Zigbee)
• XIAO ESP32-S3 Sense (Camera/SD card)
• Other XIAO ESPs are untested, but if the pinout is the same, it will work.

Possible projects:

• Meshtastic node minibadge
• Zigbee node minibadge
• Picture/video recorder minibadge
• LED matrix minibadge
• GNSS minibadge
• Temp/humidity/light sensor minibadge
• mmWave sensor minibadge
