News: RS485 ESP32 Din Rail Mounting Expansion Board DC 7-30V Power Input 5V 3.3V Output for WIFI BT IOT MQTT HTTP Smart Home DIY ES30485

ES30485 is a 30-pin ESP32 expansion board with RS485 bus interface produced by ELETECHSUP. It lead out all the useful pins except the 3 ports required for RS485. In addition, it also has a wide voltage step-down circuit and can be powered by DC 7-30V. When plugged into the ESP32 board, it becomes a cost-effective main control board with WIFI and RS485.



30PIN ESP32 RS485 expansion board

1 Working voltage DC 7-30V, input reverse polarity protection.

2 With DC 5V external output power supply, minimum output current 0.5A, output short circuit protection.

3 DC 3.3V/100MA outputpower supply(output only after inserting ESP32 board)

4 Lead out almost all IO ports (Except RS485 PIN IO1/IO3/IO17)

5 With high-speed RS485 interface (Baud Rate 0.05K-1000KBPS)

6 Optional industrial standard DIN rail enclosure

7 Terminal spacing: 3.96mm.

8 Terminal Blocks: Wire Range 26-16AWG, Strip Length 3.96mm, Metric M2/M2.5 Slotted Screws.

9 Size: 75 *50 * 7mm(only Board),80 *54 * 26mm(with Rail Box)

10 Weight: 32g(only Board),62g(with Rail Box)

Use:

DIN Rail Mount Screw Terminal Adapter Module for 30 PIN ESP32 Board.

With this adapter modules, you can easily extend your ESP32 projects to industrial control applications.



Notice:

1:This is just an expansion board. You need to insert a 30-pin ESP32 board when using it.

2: 1/3/17PIN is RS485 pin, not individually led out

3: The board you receive will be a Green PCB board.
