The first one is based on an Omnivision OV5693 CMOS sensor and connects to the board through its MIPI CSI 0 connector, but the second is also based on a 5MP sensor, but also comes with a microphone, and exposes a USB Type-C port for connection to the SBC. The first one is a 10.1-inch display with a capacitive touchscreen and 1280×800 resolution, which should connect to the 4-lane MIPI DSI connector on the board via a small adapter board and a flat cable. The 16GB RAM version of the LicheePi 4A brings a feature that’s impossible not available on the Raspberry Pi 4B even though the Broadcom BCM2711 SoC is limited to 8GB supports up to 16GB RAM.Īs noted in the introduction, the LicheePi 4A also got a metal enclosure and other accessories. We’ve already discussed performance in our article about the Sipeed LM4A T-Head TH1520 RISC-V module found in the LicheePi 4A SBC and benchmarks like Dhrystone, Coremark, and GeekBench 5 show a performance very similar to the one of the Raspberry Pi 4, sometimes faster or slower depending on the workload. You’ll find all images on the wiki, but note that as with other RISC-V platforms software is still a work in progress.
OpenWrt and Android images will also be released by the company, and a few third-party images are also offered by the community. Sipeed currently provides a Debian image based on Linux 5.10 and built with Yocto, but Linux mainline support is being worked on.
While pricing is quite different, the LicheePi 4A was launched as a RISC-V alternative to the Raspberry Pi 4 SBC, so here are the specifications of the two boards side-by-side. LicheePi 4A in its metal enclosure (aluminum) LicheePi 4A SBC Since then Sipeed also started selling an 8GB/32GB model, and now a new version of the T-Head TH1520-powered single board computer is now available with 16GB LPDDR4X and 128GB eMMC flash for $179 plus shipping. The Lichee Pi 4A board was first unveiled in December 2022, before the beta version launched in May 2023 with 8GB RAM and 8GB flash.
LicheePi 4A quad-core RISC-V SBC is now available with 16GB RAM and 128GB eMMC flash, and Sipeed has also introduced various accessories such as a metal enclosure, a 10.1-inch touchscreen display, a PoE module, and a camera module.
