Description The M5Stack ATOMIC RS232 Base is a TTL-to-RS232 level conversion base for ATOM series controllers. SKU M5-A136 is supplied as the RS232 base only, without an ATOM Lite or other ATOM host. It helps ATOM projects communicate with RS232 industrial equipment, serial instruments, legacy controllers, PLC-related devices, and peripheral systems that use the RS-232 serial communication standard. The ATOMIC RS232 Base uses a MAX232 level conversion chip for bidirectional TTL-RS232 conversion and full-duplex serial communication. It also integrates an A0Z1282CI DC-DC step-down regulator, allowing an external 12V supply to be converted to 5V for powering the connected ATOM controller. The VH-3.96 4P external port provides a robust wiring interface for RS232 signal and power connections. Features M5Stack ATOMIC RS232 Base, SKU M5-A136, for ATOM series RS232 serial communication projects. Base only: ATOM Lite, ATOM Matrix, ATOMS3, or other ATOM host is not included. MAX232 level conversion chip supports bidirectional TTL-to-RS232 and RS232-to-TTL conversion. Full-duplex RS232 communication for industrial control nodes, serial equipment, instruments, and automation devices. Integrated A0Z1282CI DC-DC step-down regulator supports 12V-to-5V power conversion for ATOM power supply. VH-3.96 4P external terminal for RS232 wiring and field installation. PinMap includes 3V3, UART_TX, UART_RX, 5V, and GND for ATOM host connection. Compatible with M5Stack ATOM series hosts and supported by Arduino, UiFlow1, and UiFlow2 workflows.

Connecting M5Stack ATOM projects to legacy RS-232 instruments, sensors, terminals, and controllers. Serial debugging, data collection, automation prototypes, and RS232 protocol experiments. PLC-related testing, factory equipment monitoring, and embedded communication gateways. Projects that need an ATOM-compatible TTL-RS232 converter with external 12V-to-5V power conversion. Product List 1 x M5Stack ATOMIC RS232 Base, SKU M5-A136 1 x HT3.96-4P terminal connector Other Content RS-232 defines electrical characteristics and signaling for serial communication between computers, controllers, instruments, and peripheral devices. The M5Stack ATOMIC RS232 Base converts ATOM UART-level signals through MAX232 so an ATOM host can communicate with RS232 devices. Use the correct TX, RX, GND, and power wiring before connecting field equipment. The M5-A136 ATOMIC RS232 Base does not include an ATOM controller. Pair it with a compatible ATOM host and use the official Arduino or UiFlow resources to build RS232 send/receive tests, serial bridges, or industrial control nodes. Resources M5Stack ATOMIC RS232 Base official documentation Atomic RS232 Base Arduino Quick Start Atomic RS232 Base UiFlow test example Atomic RS232 Base UiFlow2 documentation MAX232 datasheet A0Z1282CI DC-DC regulator datasheet FAQ Does M5-A136 include an ATOM Lite? No. M5-A136 is the M5Stack ATOMIC RS232 Base only. ATOM Lite, ATOM Matrix, ATOMS3, or another compatible ATOM host must be purchased separately. What chip handles the TTL-RS232 conversion? The ATOMIC RS232 Base uses the MAX232 level conversion chip for bidirectional TTL-RS232 conversion. Can this base power the ATOM from 12V? Yes. The built-in A0Z1282CI DC-DC regulator supports stepping an external 12V supply down to 5V for the connected ATOM controller. What is the connector type? The external port is VH-3.96 4P. Confirm TX, RX, GND, and power wiring before connecting an RS232 device.
