CamCruiser reloaded - M4 + Quatos
Posted: Mon Dec 08, 2014 8:55 pm
Hi,
let me start a new build log on a second CamCruiser that is under construction. This one will use a M4 instead of the AQ6, different motors and Quatos instead of PIDs.
Will continue to post in 'picture book style' since I will need the weight of all components for Quatos later --> you will see my kitchen scale quite often
Let's start with the heart of the new copter - my new Mav2Telem 0r2 'main board'. It's similar to the one I'm using in my other CamCruiser, except that it now features an expansion connector and carries an M4 adapter PCB.
For those asking their selfs what this board is good for:
- 5V/3A switching DC/DC, Vin = 42V max.
- 12V/1A switching DC/DC, Vin = 42V max.
- 3.3V/0.5A DC/DC (LDO)
- up to 8 powered CAN slots (4 on TOP, 4 on BOT)
- 5 IntelliLED WS2812B ports for signalling
- MavLink input (via expansion header from M4)
- Spektrum X-Bus interface for connecting to TM1000 and/or other sensors (simulated telemetrie sensors)
- HOTT telemetry output
- Current sensor input (for use with current sensor on external PDB/breakout board)
- Arduino ProMicro socket for ‚Mav2Telem‘ project
The M4 expansion boards adds:
- 4.2V LDO for VCOM (supplied to the M4 via M4's expansion header
- uSD socket
- Spektrum sat connector for 2. sat receiver
- TM1000 connectors (data port, voltage sensor) to simplify wiring

- Side view on the uSS socket and the 3V3-level interface for Bluetooth. A 5V level connector is on the bottom of the Mav2Telem 0r2
- Mav2Telem 0r2 top view - the expansion connector holds all relevant signals, including CAN (for future use).
- Bottom view of the mating M4 adapter board. This features connectors for 2 additional PWM signals, Spektrum TM1000 telemetry transmitter, a second Spektrum Sat, uSD card, VCOM LDO, ...
- M4 connected to the boards. In case of the M4 beta boards (M4r4 and M4r5) only the CAN bus needs to be connected to the main board, for the M4 V2 a second wire is needed to sense the LiPo voltage (since V2 has integrated LiPo voltage divider) --> swapping the M4 between frames is quite easy!
