Kami: e-paper badge

Reference badge design for Badge.Team.

• Red/black 2.9" e-paper screen
• ESP32 with PSRAM
• USB-to-serial converter
• 6 addressable LEDs
• 2000 mAh LiPo battery (MCH2022 compatible)
• MPR121 touch button controller

(Almost) fully compatible with the older Badge.Team software, minor tweaks are needed though. Support for the new badge-bsp component is partially done, screen and LEDs work, MPR121 driver needs some love.

Note: this is a single production run project intended to provide a reference platform to play with.

Comes with a 3d printed desk stand.
