SKU:U041
PbHub Expander unit is a single-bus board which is controlled using GROVE PortB connector (The black port on the M5Go Base). The expander unit contains 6 ports all in 1 unit. PortB can be used as GPIO and Analog in (the two data lines are connected to GPIO36 and GPIO26 on the ESP32 module).
Similar to the PaHub Unit, the PbHub provides solution for multiple devices control using a single port - PortB. With PbHub each of the IO can be configured as input and output, it has a built-in MEGA328 MCU with a simple driver firmware installed.

, and the corresponding ADC resolution is 10bit
(1024), so when using an analog signal input with an input range less than 5V, it will not reach the maximum The value is 1024. 1.EasyLoader is a precise and fast program writer which has a built-in functionalities related to the 4-Relay unit. The Easyloader program can burn the firmware to the main controller board by simple easy to follow steps.
2. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click "Burn" to start burning. (For M5StickC burning, please Set the baud rate to 750000 or 115200)
3. Currently EasyLoader is only suitable for Windows operating system, Please install the corresponding driver according to the device type.
