RP2350 1.8" AMOLED Touch Display Dev Board (368×448)

An RP2350-based AMOLED 1.8" touch display dev board with USB-C, LiPo charging (battery optional), onboard IMU, MicroSD slot, RTC, audio codec, speaker, microphone and more!

---

This little display dev board is based on the powerful Raspberry Pi RP2350A with its dual-core, dual-architecture support and flexible clock running up to 150 MHz. This is backed up by 520KB of SRAM, and 16MB onboard Flash memory.

The display is a 1.8" 368x448 AMOLED touch panel, offering 178° viewing angles, 16.7M colours and touch support via I2C.

Programming and wired power is handled by USB-C, with the option to connect a MX1.25/PicoBlade-compatible LiPo battery (or grab the version that comes with a battery sized perfectly for the case). There are also pads to solder a backup RTC battery directly to the internal PCB.

Additional features include a 6-axis IMU consisting of a 3-axis gyroscope and 3-axis accelerometer, and a real-time clock with battery backup pads. Audio is output through a built-in speaker driven by an audio codec and amplifier. A MicroSD slot is provided for storage, and the board is equipped with BOOT and PWR buttons.
