M5Stack ATOM RS485- ATOM Lite development kit + RS485 converter

Description

M5Stack ATOM RS485 is ATOM Lite development kit complete with RS485 converter based on SP3485EE chip.

ATOM Lite is a compact development kit from the M5Stack series equipped with an ESP32 Pico. It has a USB type C interface, a programmable button, the ability to communicate in infrared, an RGB diode and a connector with derived GPIO pins. The M5Stack ATOM Lite can be programmed via Arduino and UIFlow (using Blockly, MicroPython language).

The set includes an RS485 converter that can work with the ATOM Lite and ATOM Matrix sets. The converter is based on the SP3485EE chip. It allows you to connect to development kits devices controlled by the RS485 bus. It is equipped with a Step Down converter that allows you to convert the voltage of 12 V RS485 to 5 V, thanks to which the ATOM set does not require additional power via the USB type C connector.

RS485 is a standard that specifies the electrical characteristics of controllers and receivers for use in serial communication systems widely used in industry. It facilitates long-distance communication in environments with electrical noise. The full documentation of the kit is available on the product page.
