Overview
The Yuzuki Rosetta
 
is a low-cost Linux development board based on the R328-S3 chip. It features dual-core A7 processors, 128MB of RAM, NAND Flash, Wi-Fi & BT
 

Cortex A7 * 2
DDR3 128MB
XR829 Wi-Fi, BT
MEMS
Audio Codec & 3.5mm
RGB LED, WS2812
CH343P UART to USB
SPI, and an 18-pin TFT LCD

 
 
. The manual is available at: https://github.com/YuzukiHD/YuzukiRosetta.
 
The R328-S3 chip was widely disassembled and costs approximately 4 RMB per chip (some used chips may have burned-out eFuse fuses, so purchase with caution). Therefore, this chip was chosen to build this development board. The rough estimated cost is 35 RMB (however, the gold plating here will definitely cost more than 35 RMB).
