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

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: […]
