美国的著名的西雅图机器人社区最近为机器人同好们设计了一款专用控制器Axon。不同于市场上其它多功能控制器,比如最近超火的Arduino,Axon是John Palmisano根据他玩这么多年机器人经验专门定制的。
Axon去掉了一些其他控制器多余的功能,重点在于其端口数量。Axon提供了55个IO, 6个计时器,16路模拟输入,4路UART,18路中端。从端口数量来说,一块Axon相当于3块Arduino呢。更重要的是100%开源。下面是Axon的规格表:
- 55 I/O Total
- Up to 16 ADC
- Up to 29 Servos
- I2C, SPI
- 3 UART
- Serial to USB Converter (4th UART)
- Up to 18 interrupts
- Up to 9 PWM Channels
- 64KB Flash, 4KB EEPROM, 8KB SRAM
- 16 MIPS throughput at 16 MHz
- 6 Timers
- Comes already programmed with a bootloader, so no programmer required
- built in power bus
- all software is free
- 100% open source
- windows, mac, and linux compatible
售价为150美金,约为1200人民币左右。好像还没有3块Arduino划算哦。(注,一块Arduino零售价大约220元人民币)
