Sipeed Lichee Pi 4A is a modular RISC-V mini PC with up to 16GB RAM
Sipeed’s Lichee Pi 4A is a compact computer that the company says offers better performance than a Raspberry Pi 4. But it has a few key features that set it apart from Raspberry Pi’s devices.
First, the Lichee Pi 4A is powered by a RISC-V processor. Second, it supports up to 16GB of RAM. And third, that memory and storage is actually part of a LM4A system-on-a-module that connects to the Pi 4A carrier board. You can use that same module with other upcoming Sipeed products including a router kit, cluster board, tablet, and phone.
At the heart of the LM4A module is an Alibaba T-Head TH1520 processor. It’s a 12nm RISC-V chip with Xuantie C910, C906, and E902 cores, and up to 4 TOPS of AI performance.
The module also supports up to 16GB of LPDDR4x-3733 memory and up to 128GB of eMMC storage, among other things.
The LM4A module is designed to slot into carrier boards like a stick of RAM, and the first board to support the module is the Lichee Pi 4A, which provides plenty of I/O options including;
- 2 x Gigabit Ethernet ports (with PoE support)
- 4 x USB 3.0 Type-A (5 Gbps) ports)
- 1 x HDMI 2.0 (4K/60fps support)
- 1 x 3.5mm audio
- 1 x 20-pin header
- 1 x USB 2.0 Type-C (power only)
- 1 x microSD card reader
- 1 x 5V DC power input
The carrier board also features a WiFi & Bluetooth adapter and MIPI-DSI and MIPI-CSI connectors for displays and cameras.
- Lichee Pad 4A with a 10.1 inch display
- Lichee Phone 4A with a 6 inch screen
- Lichee Router 4A with a compact chassis, antenna, and optional WiFi 6 support
- Lichee Cluster 4A mini ITX board with slots for up to 7 LMA4 modules, 8-port Gigabit Ethernet switch, and individual SB and SD cards for each module
