U040-B

PaHUB2 SKU:U040-B Description PaHUB2, is an I2C Expandable Hub, which can expand a single I2C HY2.0-4P interface and connects up to 6 I2C channels. It allows you to mount slave devices with the same I2C address (by polling control the different channels to achieve in-device coexistence). Embedded PCA9548AP-I2C multi-channel switch IC, Save you worries with insufficient I2C interface of the expansion. Note: When it's connected, the PaHUB2 will be polling control the different channels to achieve in-device coexistence. Please pay attention to the order of channels when programming. Product Features o I2C HY2.0-4P PORTA expansion o 2x LEGO compatible holes o Support multiple nesting o 1-6 expansion Please refer to the schematic and PCA9548AP data manual, the Unit can modify the I2C address of the device by adapting the level combination of A0~A2 pins. (The default address is 0x70) 3 Position of Welding patch are reserved on the PCB board of the Unit, A0-A2 respectively, as shown in the figure below. After welding the 0 ohm resistor, the corresponding pin will change from low level to high level. The pin level combination and its corresponding I2C address are shown in the table below. Include o 1x Pahub2 Unit o 1x HY2.0-4P Cable Application o I2C device expansion Specification Specifications Parameters Channel Control IC PCA9548AP Communication I2C: 0x70 (can be modified by resistance A0, A1, protocol A2) Net weight 7g Gross weight 19g Product size 48 * 24 * 12mm Packing size 67 * 53 * 12mm Schematic Related Link o Datasheet o PCA9548AP EasyLoader Click to download EasyLoader 1.EasyLoader is a concise and fast program burner, which contains the test program used by Pahub2 & M5Core. https://docs.m5stack.com/en/unit/pahub2
