Crowpi2 hardware in pictures
Screen driver - converts HDMI to screen.
Fan - right above naked SoC on Pi board.
Led indicators on all Pi connector pins.
Relay
Re: Crowpi2 hardware in pictures
SPI / CE1 to Rocker ?
GPIO to PIR, Sound detector - not entirely sure what GPIO28 is doing.
Ultrasonic - Trig and Echo
Tilt and Temp / moisture on GPIO pins
Power conditioning at the top.
Re: Crowpi2 hardware in pictures
I2C on connector.
Servo connector.
Stepper connector - drivers below it.
Buzzer - and PIR circuitry ?
Vibration, Sound, Touch.
8x8 colour matrix
4x4 button pad - quite sturdy.

Light sensor on I2C
RFID on SPI
Re: Crowpi2 hardware in pictures
It came with power adaptors for Pi4 (USBC) and Pi3 (microUSB)
There is also a connector for HDMI - one for Pi3 another for Pi4
Tray is way too small for a battery pack - still thinking what to do about that
Fan a teeny bit noisy - maybe a heatsink on the Pi is enough - the fan pops out, I guess the heatsink would just go in its place

"not entirely sure what GPIO28 is doing"
if it the same/similar as the original crowpi it came with a small remote control and an ir receiver (looks like a transister with a lump on the front, some have a metal case on them) plug that in to the connector and write some code and you have a functioning remote control
how good does the keyboard sit on the device (they had problems with that in pre-production, something was warrped on it)??

Re: Crowpi2 hardware in pictures
You are right - it came with VS1838B - which is an IR receiver IC. Thanks for telling me where to put it ..
The keyboard is snug - a bit of a fight to get it out - but conversely does not drop out easily.
I am busy breaking things by making a kernel with PREEMPT_RT.
I am more familiar with Arduino - so I am keen to see how they stack up.
Cheers, Andy!

Re: power supply - I have questions :-
* Is the 12V -> 5V converter on the sensor board? (I think I see power components there)
* Is it a switching regulator, or a linear regulator ?
* What is the maximum input voltage (i.e - can I put 19V into it ? Are there sensors directly connect to this supply ?)
I would like to take the case apart, but I am not sure if it comes apart from the feet, or below the keyboard.

Re: Crowpi2 hardware in pictures
most of the sensors use 3.3 and 5Vdc and are usually powered from the GPIO pins (with a max current draw of about 16mA)wizzy wrote: ↑Tue Nov 10, 2020 10:10 am Re: power supply - I have questions :-

but Guessing with this many sensors they must be providing power for the onboard power supply!
