Description:
1. The digital-to-analog conversion expansion board specially designed for Raspberry Pi can make up for the lack of control of analog quantity by Raspberry Pi, and select the right accuracy to meet most of the daily development needs.
2. Make full use of the Raspberry Pi GPIO resources to expand all the Raspberry Pi GPIO pins.
3. Through the PCF8591 of the I2C interface, the analog IO is simulated and expanded without occupying the Raspberry Pi GPIO resources.
4. Resource integration, optimizing product appearance, and improving development efficiency.
5. Gold-plated pin headers, sophisticated materials, stable electrical performance. Optimized PCB trace layout and component layout, the port labeling is clearer and clearer.
Specifications:
1.Output voltage: 3.3V/5V (IO port VCC: 3.3V)
2.Analog interface:
Input: Four-way analog quantity is converted into digital quantity AD input
Output: One digital analog is analog DA output
3.Digital interface: 27 digital IO
4.I2C interface: 3 channels of I2C (BCM2, 3 pins)
5.Serial port: 1 channel serial port (BCM14\15 pins)
6.SPI interface: 1 channel SPI (BCM7, 8, 9, 10, 11 pins)
7.Pin: for Raspberry Pi GPIO
8.Size: 35*56*24cm
Note:;
- There might be little error of size for manual measurement.
- The colors deviation might differ due to different monitor settings, please kindly understand.
