fritzing file of the OBAL board #15

Closed pghpete closed 2 years ago

pghpete commented 2 years ago

I'm in the process of soldering up my board, attaching components and determining additional wiring. I was wondering if you had a fritzing file for this board? It would be extremely useful. If you don't or don't have the time, I may try to find the time to learn how to convert this or generate one.

I use easyeda.com my boards are shared at https://oshwlab.com/mohammad.hefny?tab=project&page=1 It is an easy free app BTW.

Thank you. This is more for wiring various sensors to the OBAL board not the actual PCB design. If I do get the chance to create it, i'll share it here in case you or anyone else is interested in it.

Thank you. Please share your design if possible.

This is more for wiring various sensors to the OBAL board not the actual PCB design. Are you going to add extra sensors ?

I would like to see if I can't use the MPU9250 via i2c since I cannot seam to find code to properly use it on the rpi via spi. I have also added a UART expansion board HAT and a witty pi 3 (power, safe shutdown, and RTC) board to it. I believe i'll only need to move two pins via code, OBAL LED_3 move to RC8 (BCM 16) OBAL SRVO_EN move to RC7 (BCM 20)

I'll lose 2 RC channels but they shouldn't be needed for a boat with only 2 thrusters and differential steering. I'll keep you posted on the project.

You can connect MPU9250 via I2C but it will not work properly because i2c is shared with other sensors. Using SPI you can use MPU9250.

It doesn't conflict with any of the existing i2c addresses already in use... that I can see. (unless i'm missing one?) Does the ardurover code have the spi code in it for the mpu or is it a separate python module or other code?

It does not conflict. It just sometimes gives IMU temp reset much more often than SPI.

ah. gotcha. ty.
