Lichee Pi 4A(8+8GB)

There are many alternatives to the Raspberry Pi4 in the market today, some better than others and some even better than the Raspberry Pi4.

LicheePi Module 4A is the Core Module using the T-Head RISC-V TH1520 SOC, containing 4 Risc-V C910 cores and 4TOPS@int8 AI NPU inside, supports up to 16GB LPDDR4X ram and 128GB eMMC storage, supports double gigabit Ethernet and maximum 4K resolution video output.

The core also contains an additional C906 processor for audio processing. Because of the SODIMM style package, the LicheePi Module 4A can be used in various scenarios and is suitable for various types of baseboards.
