GR-LYCHEE is an Mbed enabled platform which combines the advantages of the Mbed ecosystem and Arduino UNO form factor. GR-LYCHEE includes Camera module, Wi-Fi module, and Audio codec as standard equipment.



The RZ/A1LU includes an Arm® Cortex™-A9 processor along with the integrated peripheral functions required to configure a system.

The RZ/A1LU includes a 32-Kbyte L1 instruction cache, a 32-Kbyte L1 data cache, and a 128-Kbyte L2 cache. This LSI also includes on-chip peripheral functions necessary for system configuration, such as a 3-Mbyte large-capacity RAM, 128 Kbytes data-retention RAM(shared by the large-capacity RAM), various timer functions, realtime clock, serial communication interface(UART), I2C bus interface and graphics related functions etc.
