Olimex RP2040pc

Olimex RP2040pc is an inexpensive “all-in-one” computer board based on a Raspberry Pi RP2040 MCU with support for Apple //e, Apple ][+, and Oric Atmos emulation through the Reload emulator. The board features an HDMI port, stereo audio, four USB ports, and two UEXT expansion connectors. It’s not quite the first RP2040 retrocomputing board from Olimex, as they introduced the RP2040-PICO-PC in 2021 with an HDMI port, a 3.5mm audio jack, and a microSD card slot before launching the Olimex NEO6502, which combines a MOS6502 MCU for Apple II, Oric, and Commodore 64 emulators with an RP2040 for HDMI/DVI video output and a few other things. The RP2040pc is similar to the latter, but with more ports and features, and everything is handled by the Raspberry Pi RP2040 microcontroller. Olimex RP2040pc specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133 MHz with 264 KB SRAM Storage – 16MB […]
