Lichee Pocket 4A, a portable gaming console on RISC-V

This console features a 7-inch touchscreen LCD and is powered by the Sipeed LM4A module with the T-Head TH1520 processor, which has four XuanTie C910 cores. The chip, based on the open-source RISC-V architecture, is paired with 16 GB of LPDDR4X RAM and 128 GB of eMMC storage. The chipset is also equipped with an Imagination Technologies BXM-4-64 GPU and an NPU, supporting AI performance up to 4 TOPS.

A unique feature of the Pocket 4A is its detachable Joy-Con-style controllers on either side of the console. While not offering extensive gaming capabilities, the Lichee Pocket 4A marks a step towards emulation of games for RISC-V-based systems, potentially leading to more game development for RISC-V platforms in the future.
