DC 7-24V ESP32 C3 Super Mini Expansion Board 4AI-4DO RS485 Relay Module for Ardu

Description: ESC3B04 is an ESP32 C3 Super Mini analog and relay expansion board designed and produced by eletechsup. If you know how to develop ESP32 projects, you can use it to design WIFI smart control switches, analog quantity acquisition, etc. Product Features: 1 Operating voltage: DC 7-25V(Wide voltage power supply) 2 Operating Current : Standby current 15MA, 1 relay open 74MA, 2 relays open 106MA, 3 relays open 131MA, 4 relays open 164MA 3 On-board resources: 1x RS485 Interface,4x 0-5V/10V Voltage Input(Can be used as PNP DI),1x Button Input,4x relay outputs,1x ESP32 C3 Super Mini socket. 4 size 77*72*19mm(Only Board) 5 Weight : 80g(Only Board), 144g(With DIN Box) As long as you write ESP32-C3 code,You can use it to achieve a variety of delay timer function,such as: WIFI remote control switch WIFI voltage collection RS485 Master-Slave Device(PLC MCU), 4x 0-5V/10V Voltage Collection, 4x 12-24V PNP DI Motor forward and reverse, Timing on, Timing off, Power-up delay, Trigger delay, Infinite loop delay, A finite number of cyclic delays, Power sequencer, And so on. This is an expansion board based on 16PIN C3 Super Mini. We only provide some Arduiuo codes for testing the hardware. More codes and functions need to be developed by yourself. If you need more functionality, write your own code. We do not provide additional code and technical support Tip:Vi1-Vi4 can also be used as PNP digital input. High level 11-24V, low level 0-1V (low level when suspended) Note: 1 ESC3B04 can not work independently, must be under the control of the 16PIN ESP32 C3 Super Mini board to work. 2 The package does not include ESP32 C3 Super Mini Board, please prepare it yourself
