 ## Description
 
 **BALA2** is short for 'Balance', like its namesake, it's the second generation product. **BALA2** is a Self Balancing Robot consist of a M5Stack Gray and two wheels(DC motors).The base uses STM32F030C8T6 as the main control, two-way encoding motor drive, built-in 1200mAh battery.This application product comes with preloaded software, a self-balance robot application.
-This Self Balancing Robot is a Two-wheeled Robot that balances vertically using a closed-loop algorithm. You can control it to walk freely through programming, or you can combine WiFi and Bluetooth to develop remote control functions. This Robot is controllable by a Smartphone device or a Transmitter. The BALA2 base contains a wealth of interfaces. In addition to the conventional PortB and PortC, it also supports 8-channel servos, of which 4 channels can be directly connected, and the remaining 4 channels need to be connected from the inside of the base. Even if you have never been in contact with the balance car program, you can quickly complete the programming and control it through UIFlow. Self Balancing robot uses data from the Accelerometer and Gyroscope to correct its orientation and position.The 2 DC driver module communicates with M5Stack Gray through I2C bus. It's default I2C address is **0x56**.

 ## Description
 
-**ATOM SWITCH** is a bi-directional control programable switch for the M5ATOM. It can be connected to bi-directional AC circuits for simultaneous on-off control. The on-board relay can support up to 250V / 10A AC(Instantaneous current 16A). Built in step-down module can provide 5V / 1A DC power supply for ATOM. In order to ensure safe use, its DC circuit has overheating and short circuit protection functions. In order to facilitate the use of users in industrial scenarios, an SP485EE level-conversion IC is built in. There are also a set of RS485 interfaces provided for the user to connect RS485 equipment.RS485 has the ability to supply power to ATOM, the support voltage is 9-24V. In addition, a set of HY2.0 interfaces is also provided for connecting I2C peripheral equipment or general I/O equipment. With the Bluetooth and WiFi functions of M5ATOM, you can easily setup a remote control switch. If you have multiple M5ATOM HUB SWITCH modules, you can set them up in parallel through the RS485 interface.
+**ATOM STEPMOTOR** is a stepper motor driver module suitable for Atom Lite only, with built-in DRV8825 driver chip, which can be used to drive a stepper motor. By adjusting the variable resistance, it can provide a maximum driving current of 1.2A. The chip has its own over-current protection function. A DIP switch on board can adjust the step number flexibly. Built in DC-DC,the external power supply can supply power to ATOM,drive motor needs an external power supply（9-18V).
