Description

The M5Atom Joystick is a programmable dual-joystick remote controller built around AtomS3, with an STM32F030F4P6 co-processor handling joystick, button, battery, and auxiliary control functions. The M5Atom Joystick combines two 5-way Hall sensor joysticks, two function buttons, a toggle switch, RGB status LEDs, a buzzer, and dual high-voltage lithium battery charging circuits.

Preloaded remote firmware lets the M5Atom Joystick communicate with Stamp Fly through the ESP-NOW protocol, while open firmware resources make it adaptable for drones, robots, smart cars, and other custom control projects. The compact controller also includes a 300mAh high-voltage lithium battery for portable use.

Notice: For first-time use with Stamp Fly, flash the flight firmware according to the firmware tutorial before pairing the controller for flight.

When charging through the data cable, the corresponding battery indicator shows red while charging and not full, and green when fully charged at 4.35V.

For battery care, do not discharge the battery below 3V per cell under load. Do not store fully charged batteries for more than 3 days; for long-term storage, keep the voltage between 3.8V and 3.9V.

Other Content

The M5Atom Joystick uses AtomS3 pins G39 and G38 for I2C communication with the STM32F030F4P6 co-processor. The buzzer is connected through G5, and the WS2812C RGB LEDs are connected through G6. Battery detection is handled on the co-processor side through BAT-ADC1 and BAT-ADC2.

Before using the M5Atom Joystick for flight, complete the Stamp Fly firmware flashing and pairing workflow, then verify joystick, button, charging, and battery indicator behavior before operating a vehicle or robot.

FAQ

Can the controller be used with Stamp Fly?

Yes. The M5Atom Joystick is preloaded with Stamp Fly remote firmware and communicates with Stamp Fly through ESP-NOW after the required firmware flashing and pairing process.

What input controls are included?

It includes two 5-way Hall sensor joysticks, left and right function buttons, a toggle switch, RGB LEDs, and a built-in buzzer.

How should the battery be stored?

For long-term storage, keep the battery voltage between 3.8V and 3.9V, and avoid storing a fully charged battery for more than 3 days.
