Preparation: Carefully unpack the ESP32-S3 module, e-paper screen, motherboard, and battery. Check for missing or damaged components.
Screen installation: Align the ED047TC1 screen connectors with the 8-bit parallel port on the motherboard. Insert gently without forcing to avoid damaging fragile pins.
Battery connection: Plug the JST connector of the 140mAh battery into the dedicated socket on the motherboard. Respect polarity (red/positive, black/negative).
Case assembly: Place the motherboard into the plastic holder. Tighten the provided screws with moderate pressure to avoid cracking the plastic.
Verification: Briefly press the power button. The screen should display a boot logo or a white refresh screen.
Deepening: Test connection stability by slightly moving the case to ensure no components disconnect.
