Alternate board for BGC #3

Closed dhanushmeda closed 4 months ago

dhanushmeda commented 6 months ago

Are there any alternatives for this board? Cant find this one in India! Is FOC Shield good enough for this purpose?

remrc commented 6 months ago

There are no alternatives. But you can buy it on Aliexpress or Ebay. I used this board for only one reason - it has a microcontroller and two BLDC drivers and is small. By the way, you can use Arduino and FOC Shields, but all this will take up a lot more space.

I was trying to build bgc board on my own, I need some help because there is no documentation. Along with Atmega328p, CP2102X(USB to Serial), I2C hardware, hardware for SPI, BJT's for driving motors, what else do we need to make brushless motors run? what are the BLDC drivers? I really need someone's help with this. Thanks in advance.

Doing BGC 3.1 yourself is a bad idea. It costs only ~$15. Two SimpleFOC mini drivers could also be used.

I am not able to get it in India that's why thought of designing, need to try ebay or AliExpress for delivery to India then

I got a BGC board. I am using arduino ide and i have set the board as arduino nano. I'm getting the below error.

Probably no bootloader. Ask google how to write a bootloader to atmega328. It's easy, but still requires a bit more knowledge...
