Educational kit with a 2.8" color TFT IPS display with a resolution of 320 × 240 px and adjustable backlight, ideal for game development, data visualization, and IoT projects. The device is based on the RP2350B microcontroller (2 × Arm Cortex-M33 250 MHz) with 520 KB SRAM, 16 MB QSPI Flash, and 8 MB PSRAM, and connectivity is provided by a Wi-Fi and Bluetooth module (CYW43439). A built-in 1000 mAh LiPo battery charged via USB-C guarantees mobile operation without a constant power supply. Five buttons, an I2C Qwiic/STEMMA QT connector, and MicroPython support make the kit a versatile platform for learning programming and STEM experiments. Pimoroni WARE002

An educational kit with a 2.7-inch e-Paper display with a resolution of 264 x 176 pixels and four grayscale levels, ideal for presenting schedules, QR codes, and IoT messages. The device is based on a dual-core RP2350A microcontroller (2 x Arm Cortex-M33 250 MHz) with 520 KB of SRAM, 16 MB of QSPI Flash, and 8 MB of PSRAM. Connectivity is provided by a Wi-Fi and Bluetooth module (CYW43439). A built-in 1000 mAh LiPo battery, charged via USB-C, enables long, energy-efficient operation, and the RTC allows for the development of cyclic applications. Pimoroni WARE001
