[Verified] Alternative for 8266 Receiver + AMOLED ESP32 Development Board

Revision History
2024.8.17 Modified battery protection circuit.
The T-Display-S3-AMOLED development board is a replacement for
the original AMOLED, which was too expensive,
so this module was
used. The screen used was a 1.2-inch 240x240 screen from Lao Wan, which cost 1 RMB each.
The price of this screen has increased, so a 1.2-inch 240x240 screen from Lao Wan, which costs 2 RMB each, was used instead
. The baseboard shows the ESP32 universal remote control
receiver, which

uses the 8266 protocol and esp_now.

It has been successfully tested
and has 4 channels plus 2 LEDs.
The program is still being improved.
The receiver supports a maximum of 5 seconds of battery life; if a spare battery is not used, the 4056 can be omitted. Some
videos can be found in the attachments.
The receiver has been successfully tested and verified.
This 32D is a single-core MCU customized by Xiaomi, with Wi-Fi and Bluetooth locked.
It costs 3 RMB each on Xianyu (a second-hand marketplace) and can use RF24. The remote control
display stand has been corrected in the shared project
to support two identical screen cables
. The demonstration uses the Lao Wang 1.2-inch 240*240 IPS screen with protective cover. The video cable stand is DF37NC-24DS-0.4V(51).
