After designing a case for my ESP32 WiFi scanner I’ve picked up some new parts to play with: a WeAct Studio ESP32-S3-N16R8 dev board — 16MB of flash and 8MB of PSRAM, dual USB-C, RGB status LED, sat in a little printed case I already had lying around — paired with a WeAct Studio 4.2 inch e-paper module, 400x300 resolution over a simple SPI header (GND, SDA, SCL, CS, D/C, RES, BUSY, VCC).
