- to get the data from the IMU SENS
- to communicate with the xBee-M1 for real time control
- to get instructions from the SAME70-M1
- to control the motors using the PWM signals
For the whole picture
The SAME70-M1, communicates with the SAME70-M2, and the SAME70-M2 communicates also with the RPi Compute Module.The SAME70-M1/M2 are linked to the xBee-M1/M2.
I used the schematics of the evaluation board of the SAM70Q as reference, and followed the reference manual of the SAME70 series.
Here is the first result.
This circuit will be common to the SAME70-M1/M2/R1/R2.The only differences it the use of the different ports.
The following are the ports used by the SAME70-M1.
The following are the ports for the SAME70-M2Mainly used for non critical sensors (GPS, current sensors, LiPo cells voltage sensors...)
I use a PFC connector with 30pins to link the FRONT SENS
The compute module is connected to the TOP PCB using the DDR2-SODIMM socket.
I used the schemactics from the Raspberry Pi foundation website as reference.
The compute module is powered using 1V8/3V3/2V5.
The PCB TOP will have a micro USB for programming the RPi Compute Module and a USB-A for peripherals.
I added a connector for TV DAC in case if we want to use a video streaming.
There are two camera connectors, hope to be able to set stero vision using the RPi CM.
To power the RPi CM the DCDC converters of 1V8 and 2V8 are placed on the PCB TOP.
