# VoCore
## Overview
VoCore is a coin-sized Linux computer running OpenWrt. It contains 32MB SDRAM, 8MB SPI Flash and using RT5350(360MHz MIPS) as its heart. It provides many interfaces such as 10/100M Ethernet, USB, UART, I2C, I2S, PCM, JTAG and over 20 GPIOs but its size is less than one square inch.
## Hardware
### Specs
* SoC:
- Ralink/Mediatek RT5350 MIPS processor @360MHz
- Dual band 802.11n Wi-Fi (up to 150Mbps)
* RAM: 32 MB RAM * Storage: 8 MB SPI Flash * I/O (20 GPIOs)
- Dual 10/100M Ethernet
- USB Host
- UART
- I2C
- SPI
- I2S
- PCM
- JTAG
* Power: 5V, 3.3V, 1.8V, GND * Consumption: <250mA @ 5V * Dimensions: 25×25 mm
### Pinout
The pin spacing is 1.27mm, 0.50mil
## Software
### Serial
Wire the Serial port 2 (RX2, TX2, GND) and then you should be able to connect to the board using an USB-TLL adapter:
picocom -b 57600 /dev/ttyUSB0
I ran into some issues (board freezing then rebooting, apparently because of some RAM issues) when powering the VoCore through an USB port of my laptop. It only happened when the USB adapter was plugged in. I have since tried with an external USB power supply (phone charger), it fixed this issue.
### AP+STA Wifi
