- An arduino shield adapter would be nice, so we can use arduino shields with the pyboard. As far as it is compatible, of course.
- A pyshield with ethernet and PoE support. I know Damien would bring support for the WIZ820io module once the logistics are finished, but having this module as pyshield possible with PoE support would make it very convenient to make projects that need network connectivity and to place them just somewhere (e.g. sensors or data loggers or something like that)
Expansion boards - pyshields
Expansion boards - pyshields
I'd like to open a topic to collect ideas for all kinds of expansion boards (calling them pyshields?)
Re: Expansion boards - pyshields
I thought I would mention that I've been using a Netduino Plus 2 which has an Arduino shield footprint and uses the same microcontroller as the pyboard.
I haven't added the support for the sdcard yet (its wired up as 1-bit SPI) nor the ethernet, but that will come in due course.

Re: Expansion boards - pyshields
Kenneth, I plan to do the opposite: use a pyboard as a RPI shield, in order to add some low-level tasks support...

Re: Expansion boards - pyshields
I will try to make a 10DOF IMU shield. Either using a MPU9150 and BMP180 or adapting the adafruit 10DOF IMU breakout board.

Re: Expansion boards - pyshields
Ok, so I'm working on an IMU shield. First time designing a PCB.
IMU shield
power and wireless
Interested? Are the chips ok? Other ideas?
The chips for the IMU would cost about 15€, for pwr/RF24 about 6€. 2-layer PCB the size of a pyshield is about 1€ per piece if yout take 100, 3€ with the components soldered (at least thats what their online-tool told me).
IMU shield
- BMP180 pressure/altitude sensor
- LSM9DS0 3-axis acceleromter/gyro/magnetometer
- (maybe: MMA6827 3-axis accelerometer for high g-loads)
- male pins for the 4 servo channels and pwr/gnd, so you can easily plug in servos
power and wireless
- nRF24L01+ wirless transciever
- MCP73833 lipoly charger
- TPS61090 boost converter (or similar)
- (maybe: reset and user button)

Re: Expansion boards - pyshields
@Turbinenreiter - Sounds great! Certainly an ambitious first-time project, but doable. (I won't doubt the abilities of the pyboard rocketeer…)
I will be happy to help and even review your designs if you would like; I do more board design than programming anyway. As for the chips, I haven't used or looked into any of them so no opinions on that, but I'm sure they can be made to work.
If I ever manage to code up I2S support for micropython (…he keeps saying that, but somehow nothing ever happens…) then it could be fun to put together an audio skin with a simple I2S codec.
