PWM on any of these pins?

I am currently using the TX2 through the ConnectTech Rudi enclosure and carrier board. I need to generate PWM on one of the following pins, is this possible?

Does anyone know if any of these pins can be configured for PWM?

Check out this article:

I would highly recommend adding a I2C, SPI, UART, or USB controlled microcontroller that does the PWM for you based on commands you send to it. This will cost you between $0.50 and $30 depending on how much work you want to do yourself.

Hi Snarky,

That would be fine to do if I were designing the carrier board. However, for this application I am using an off-the-shelf carrier board inside an enclosure.

Hi, please check pinmux, only pin H12 can be set as GPIO and you need to manually drive it to high/low to simulate a PWM output. The other three are dedicated pins and can not be set as other function.

You don’t need to design the carrier board yourself, you can use some small microcontroller board and hook it to whatever control pins are exposed by the carrier board you do have. Most of them have a couple of UARTs, I2Cs, and SPI at least. Some controllers can be run with just a decoupling capacitor and power, even. If you’re just making one, solder wires straight to the legs :-) Or make a very small board that can piggy-back.
