Waveshare module integrates 6-axis IMU and 1.28” IPS LCD

Dec 23, 2022 — by Giorgio Mendoza 2,196 views

The WaveShare RP2040 is an open-source embedded platform based on the Raspberry Pi 2040 microcontroller. This board is equipped with one 1.28” IPS LCD, one 6-axis IMU, various GPIOs and one connector for a 3.7V Lithium battery.

As its name implies, the Waveshare RP2040 is equipped with the RP2040 microcontroller:

The display integrated is a GC9A01A, which is a 1.28” IPS LCD display that supports SPI to communicate. 

The IMU (QMI8658C ) integrated consists of a 3-axis gyroscope and a 3-axis accelerometer. Both of these sensors offer 16-bit of resolution.

The GPIOs can be accessed via the 1.27 pitch female headers. Although, the product page specifies that some of these pins “are multiplexed to the internal circuit”. Some of the communication interfaces supported are 2x SPI, 2x I2C, 2x UART, 4x 12-bit ADC and 16x PWM channels.
