Odroid Board used for poppy humanoid (U3) disappearing some month ago, so we switch to a new odroid version (XU4). This board is excessively powerful but there is no sound interfaces and a really dirty integration into the head of poppy humanoid.
We choose to switch to RaspberryPi but USB2AX need to be mount out of the head on the usb ports. We started to redesign a new RaspberryPi based on compute module called Raspopyno, but it is relatively expensive and there is only the RaspberryPi 1 version available. You can find this work described here and a topic related to here :
After many reflexion and hesitations we abandon this project because it is a really complex and overkill one!
For Poppy ergo Jr we use RasperryPi 2 with a board called Pixl. This board manage power conversion and communication adaptation, so we should use this for poppy humanoid instead of USB2AX!
This board will be named Hipi and it contain :
- A power conversion part 12V/5V@3A
- 2 x “Full duplex 3.3V”/“half duplex 5V” converters
- Audio amplifier 3W stereo
- A tiny IMU
