This compact ESP32-S3 development board includes a 6-axis IMU and 1.9″ LCD display – with a variant option including touch control – and has a pinout compatible with the Raspberry Pi Pico, allowing the use of Pico HATs and other Pico-intended hardware!

The popular ESP32-S3 provides 2.4GHz Wi-Fi along with Bluetooth 5 LE via an onboard ceramic antenna, and comes with the usual built-in 512KB SRAM and 384KB ROM, supported by the onboard 16MB FLASH and 8MB PSRAM. The board is powered and programmed by USB-C.

The display is a small 1.9″ panel with a 170×320 resolution, 160 viewing angles and 262k colours. A version with touch control is available, select the appropriate variant before adding to cart.

Other features include a QMI8658 6-axis IMU (3-axis accelerometer and 3-axis gyroscope) for detecting motion gestures, a microSD slot, connector for a MX1.25/PicoBlade-compatible lithium battery (with charging circuit) and the BOOT/RESET buttons.

In fact, the non-touch and touch versions have a couple of other differences too:

• The non-touch version includes a WS2812 RGB LED on the underside
• The touch version includes an IPEX1 connector for using an external antenna (resistor resoldering required to enable)
• The touch version includes touch input (but you knew that already!)
