Orange Juice - An Orange Pi Zero klipper extention board

thingiverse

If you like me, is using orange pi zero/zero2 as the klipper host for the printer, then this "Orange Juice" may give you some conveniences. ;) Here are two version, one for orange pi zero and another for orange pi zero2. They have different board size but with same BOM meterials. You can find more information and release with link below: https://github.com/jeji/orange_juice Both Orange Pi Zero and Zero2 even with 512MB memory version is overkill as a klipper host. I'm using them for a year without any issue. And Yes, installation is little bit complex than Raspberry Pi but KIAUH makes it a lot of easy. Klipper has some advance features which need connect to gpio pins, it's not that comfortable to use a pin header to connect gpio pin every time. With this board, it provides easier connection and more useful features: - A dedicate [ADXL345](https://www.adafruit.com/product/1231) port is extended from OrangePi zero SPI1 bus - A dedicate MAX31865 port connect to 4 gpio pins as a SW SPI connection, for [Adafruit MAX31865 board](https://www.adafruit.com/product/3328) or its clone - Two USB2.0 Type A ports are extended from orange pi function pin - A UART port for UART communication with printer MCU board - Three klipper controllable pwm output ports, voltage depends on input DC voltage - Three gpio port from orangepi with 5v power, for custom function - Two 5v output ports - A built-in 3010 chip cooling fan position - A built-in step-down buck converter to convert DC 9~24v input to DC 5v to supply pi and 5v output socket - Raspberry Pi B Serials board size and mount hole position compatible - 0805 or larger size SMD components are being used for hand soldering https://www.youtube.com/watch?v=ZA7Z6DOhGXk
