Re: CJMCU microquad board

I just added nrf24l01 support (only with WLToys V202 ptotocol for now), it should make its way into trunk soon.

Note that on Rev1 board SPI1 connector is rotated 180° compared to the v2, not very convenient:

Re: CJMCU microquad board

Problem with led strip is that there's no TIM3 output broken out on the board, only TIM1 & TIM2 which are already used.

I haven't touched it for a while, it works but doesn't fly near as well as multiwii/baseflight.
If you've got a spare hubsan x4 or v202 or jxd FC give it a try :)

Re: CJMCU microquad board

The pads on one of the arm are wired to SPI2, looks like SPI1 (PA5, PA6, PA7) is not broken out on the board.

Re: CJMCU microquad board

I haven't tried yet, but I was planning to do it, I installed a nrf24l01 into my Devo TX a few days ago...
You can find source code for wltoys V202 compatible RX here:

I guess you are alright regarding the small length and wide arms, tomorrow I'll put it into a mQX frame (geared 8.5mm motors).

Re: CJMCU microquad board

Sat Vcc is connected to 3.3V pad, what you think is a wire in the (bad) picture is the "2" silkscreen.

MAG doesn't work when motors are installed, they are too close from the sensor.

Cool, I might implement Flysky RX when I have a chance, so it could be used with a WLToys or moded Deviation radio.

Re: CJMCU microquad board

try
map TAER1234
if it still doesn't work, try serialrx_type = 0 instead of 1.

Re: CJMCU microquad board

Looks like the firmware you're using doesn't have serial rx support, try to flash the one I uploaded in the previous post.
(don't forget to remove BOOT0 jumper ;))

Re: CJMCU microquad board

I did replace the 20Kohm gate resistors with 200 ohm ones. Now it lacks power, needs 75% throttle to hoover, it doesent "shoot up" like the pocketquad with the same motors / props, it "creeps up". I have no idea if this is related to the gate resistors, or it's my lipo going bad...

Re: CJMCU microquad board

Hi guys. It's frustrately enought, but my quad continues to remain on the ground. I've tried both firmware, from mj666 and dominicclifton, both flash on OK, baseflight configurator see a quad,... But I can not make arming. I've tried two receivers, spectrum AR6200 satellite connected SER to PA3 and...

Re: CJMCU microquad board

I wonder why they threw a mag at this board, it can' work because motors are too close :lol:

Re: HEADHOLD and HEADFREE without a magnetometer

I reimplemented magless headfree & headhold over Plüschi's code with high resolution gyro/acc a few months ago but it doesn't work really well, I probably missed something.

Re: Atmega328 with fet output for motor brushed

Thanks Alex.

I'll have a look to see if it's possible to have EXT_MOTOR_xKHz for 6 motors on the 32u4.

Re: Atmega328 with fet output for motor brushed

Thanks,
20k resistor on fet gate is what is used on the HK pocket quad ;)

I'll have a look at the at32u4 datasheet.

Re: Atmega328 with fet output for motor brushed

Plüschi, do you know if the at32u4 (or m328) could output 6 or 8 high frequency PWM signals for brushed hexa or octo ?

Re: Atmega328 with fet output for motor brushed

+1 Plüschi, this code makes wonder with at32u4 + brushed motors, that's what I'm using on the HK pocketquad and frankemQx
