IoT relay control board

Overview

Version 1.1 --> 2.1

adds support for 433 remote control module (SYN480R) .

Version 1.0 --> 1.1 updates include

optimized wiring between some components
, upgraded 3.3V power supply, improved power supply capability for ESP01
, firmware optimization, and support for DHT11 connection .

1. Power

Supply: Minimum voltage 12V, maximum 80V

. 2. Design:

Integrated 4-channel ADC input with 10K pull-down resistors for connecting NTC and other sensors.
Integrated 7-channel relays, allowing selection of normally open and normally closed connections.
Relay control and ADC data reading via serial communication.
Integrated ESP01S docking station for direct internet access.
UART1 and ESP01S cannot be used simultaneously; only one can be used.

3. Firmware:

Firmware is not open source
and lacks a reset button; a flashing program must be connected before powering on.
Firmware is downloaded via UART0.
