ESP32LR88 - WIFI 8 x 16A relays

Devantech

Overview

The ESP32LR88 is a WIFI connected relay module using the popular ESP32. It provides 8 relays capable switching up to 16Amps and 8 digital inputs with pull-ups than can interface directly with volt free contacts. The normally open relay contacts have snubbers fitted across them, and can drive inductive loads such as contactors and solenoids. Power for the board is 12v dc, which can be provided by a standard universal wall power supply. A 1A or greater supply should be selected.

WiFi

The ESP32LR88 connects via WiFi to your network. Therefore it must be located in a position where it gets a good WiFi signal. The module should not be enclosed in a metal box/cabinet as this will shield the WiFi signal. You can check the signal level by looking at the RSSI figure which is reported by the ST (STatus) command.

Configuration

The ESP32LR88 is configured by connecting a USB cable to your PC and running a terminal program. PuTTY is a good option if you don’t have any other preferences. The serial port should be set to 115200 baud, 8 bit, 1 stop, no parity, no flow control.
