Balloon - Open Hardware development boards
开源文档
Introduction
|
Balloon is an Open hardware development board intended for use as a computing module in embedded devices, development projects or educational settings.
Balloon should be viewed as a versatile 'computer component'. Most projects need their own bit of hardware or IO. Balloon means you can concentrate on that part and add it on to the base Balloon. Balloon has the CPU, RAM, NOR and NAND Flash, serial, USB client/host/OTG, I2C, Compact Flash, IO header, buffered expansion bus, simple 8-bit bus, and a CPLD or FPGA. It is particularly suitable for battery-powered devices, wearable computing, low-power instrument monitoring, robotic control and university or corporate research needing physically small, lightweight (<30g), low-power(<1W), high-performance computing.
