BANDIT PC32 standalone ColorForth keyboard computer is powered by the Raspberry Pi RP2350 microcontroller

BANDIT RP2350 computer

BANDIT PC32 is a Raspberry Pi RP2350-powered keyboard computer that runs a graphically-oriented version of the ColorForth programming environment. The BANDIT PC32 is primarily aimed at on-the-go use for programming video games. The custom, 32-key split keyboard takes up most of the build, with a 3.2-inch 320 x 240 capacitive display in the center. It also features an HDMI port for connecting a larger external display. The 48-pin GPIO is divided into two female headers and can be used to interface with other devices directly. This is the second version of the Bandit standalone computer, building on an early prototype based on the RP2040 microcontroller. We have seen several interesting RP2350-based products like the Inky Frame 7.3”, 4D Systems display modules, and Jumperless V5 programmable breadboard. However, this is the first RP2350 standalone computer we have come across. It shares some similarities with the ESP32 Rainbow. BANDIT PC32 ColorForth specifications: […]

Inky Frame 7.3-inch ePaper display

The Inky Frame 7.3″ is a Pico 2 W ePaper display featuring a 7.3-inch E Ink screen with 800 x 480 resolution and 7-color support. Other features include five LED-equipped buttons, two Qwiic/STEMMA QT connectors, a microSD card slot, and a battery connector with power-saving functionality. This Pico 2 W ePaper display is ideal for low-power applications such as home automation dashboards, sensor data visualization, and static image displays. E Ink technology ensures energy efficiency by consuming power only during screen refreshes while retaining images when unpowered. Flexible mounting options and included metal legs make it suitable for various setups. Previously, we covered the Waveshare 4-inch Spectra, a six-color ePaper display, along with other modules like the Inkycal v3, Inkplate 4, EnkPi, Inkplate 2, and more. Check them out if you’re interested in exploring these products. The Inky Frame 7.3″ specifications: Wireless module – Raspberry Pi Pico 2 W SoC […]
