New product post - IIC GPIO Module
When use Arduino to make robots or perform interactive media, have you found digital IO ports are not efficient? Arduino UNO and Leonardo often face this problem. How can we make use of existing resources to expand sufficient Arduino ports? Now we are able to solve this problem through our currently - released new product, IIC GPIO Module. This module can achieve communication through Arduino two IIC data lines (SDA / SCL), thus convert the readable and writable 16 channel digital I / O port, therefore, have a look.
IIC GPIO Module can achieve communication through Arduino two IIC data lines (SDA / SCL) with our IIC GPIO module, thus convert the readable and writable 16 channel digital I / O port. In addition, 8 modules can be simultaneously in parallel, and each module can be set to different IIC address, through which you could parallel multiple modules for data acquisition and control according to the demand of project digital ports. A total of 128 digital ports are spared, double of MEGA2560. If you can’t use I2C, SPI or other protocols, it is necessary to equip with an expanded version of IO.
Connection: VCC-5V GND-GND SDA-A4 SCL-A5 (INT for I / O interrupt interface) A0, A1, A2 for setting different IIC addresses when connected in parallel with other modules(0X20-0X27).
1、When in connection, do it as the way we provided（Do not make mistakes between VCC and GND）
2、When multiple modules in parallel, connect the Jumper wire and Short Cap according to your set module address.
- Module power supply: +5 V
- 16 Digital IO port comes with internal pull-up
- Can be set to eight addresses (address range of 0x20 ~ 0x27)
- 8 modules simultaneously in parallel (IIC bus need to pull together)
- Module Size: 42X34mm
Do you like the GPIO module to cool your project? By the way, several days later, we would launch a series of Raspberry Pie products, interesting and practical, stay tuned.
