About the Adafruit ESP32-S3 8MB No PSRAM PCB
Adafruit ESP32-S3 8MB No PSRAM is an open source ESP32 PCB design by cgallizzi, published on GitHub under the MIT license. It is a 2-layer board measuring 50.8 × 22.9 mm, with 44 components from 29 distinct parts.
Its main chip is the LC709203F/MH, from the ESP32 family. Other key parts include the ESP32-S3-MINI-1, AP2112/RT9080-3.3, MCP73831T-2ACI/OT and BME280. By type, the board carries 11 capacitors, 10 resistors, 8 ICs, 2 crystals, 2 jumpers and 2 switches.
It belongs with the displays & leds and dev boards & breakouts designs in this gallery.
From the project
Steam Machine e-ink faceplate with a Now Playing mode: box art, playtime, achievements. Fork of Valve's Inkterface.
An e-ink faceplate for your Steam Machine that shows the box art, playtime, and achievement progress of whatever you're playing — plus all the original system telemetry readouts.
Now Playing artwork mode: when you launch a game, the panel switches to that game's box art with your total playtime and achievement progress rendered next to it (dithered for the e-ink look). When you quit, it goes back to the regular telemetry layout. Toggle it with the Box Art button in the configure screen. Game collectors: Game Time and Achievements readouts you can put in any panel field, alongside the stock…
