ideaspark ESP32 with 1.9" LCD

$12-18

Classic ESP32 (no PSRAM) with a 1.9" 170x320 ST7789 LCD. Muse shows status and draws images straight to the screen, but there is no home-network tunnel. Needs chip rev 3.0+ for signed apps (the D0WD-V3 qualifies). Cheap, bare PCB, no case.

Limits

Good to know

Boards without PSRAM (classic ESP32, ESP32-C6) run without the home-network tunnel; Muse can still reach and control them.
Pairing has no manufacturer verification and can't prevent an active man-in-the-middle attack.
Builds are signed with the included development key and never enable Secure Boot. Enable NVS encryption (CONFIG_HOMEHUB_NVS_ENCRYPTION).
Custom ESP32 commands are not a documented API yet: the command set (display.draw_url, sensors.read, camera.capture, ...) is hardcoded in main/app.c.
