Request to Radxa - CM5 - NANO Board Please

#1

Radxa - Tom Cubie , Yuntian.

CM5 with CM4 Nano is dope but… CM4 Nano from waveshare has a bugger flaw where we cant connect easily an dam fan via dc pin connector other than on GPIO.

I didn’t wanted to use GPIO because its another pump on the board size with a clear cable positioning that sucks.

On idle things can stay around 65ish degrees.

Max temperatures are 86C and it can be reached easily and too quickly with just an metal heatsink.

I just wanted an nano carrier board like the waveshare one for a minimal board.

Would yous consider my request to design an carrier nano board with maybe:

  • Mini or Micro HDMI
  • 1 usb port or 2
  • 2 USB
  • MicroSD slot
  • Maybe an AIC8800?
  • DC connector for that needed fan heatsink

Just so we could connect the Module to that neat basic Nano board and take it anywhere and be as plug and play as it gets?

I love this thingy but at 80C while doing some cloud gaming makes me lose my mind :\

If only the CM5 had a fan connection slot for the fan…

I would cut the JST connector from the Heatsink fan and then solder it to the GPIO pin (to avoid the increased height with the header).

Then write a small program for PWM control of the GPIO pin connected to the fan and monitor the cpu temperatures to vary duty cycle (fan speed).

Can you solder?

Sounds like a possibility I didnt knew that could work without the gpio spikes soldered…
I could buy some cheap solder for that but… a better product would always provide better results :confused: I can imagine myself getting the ‘wrong/undesired’ fan soldering and then what? To replace it needed to mess about that more till I wrecked it probably…

Would be so bad to ask yous to please make an upgraded version of the cm4-nano for the radxa cm5 with fan connector ?

#7

CM4 Nano is not our product. We currently have no plan for this type of product, since 2 PCBs result in higher total cost.

#8

Exactly for the reason is isnt… that I am asking if yous could consider designing one with upgraded features.
I would def buy it and I know a few others that would too.

I understand the issues… but to me a small sized module like the radxa Compute Module 5 would make more sense a tiny carrier board matching its design.

#9

It’s one thing to have an existing & verified design and make upgrade, and another thing to design a new product. CM* are not really end user facing products, so the potential users for the tiny baseboard are very niche. We have ZEROes for small form factor.

#10

Just not yet zeros with the 3588 but yes… I do understand that… Im sad… but… I will be patient.

#11

connect ur fan to + and ground on the gpio. imagine asking for a whole board to be made because you don’t know how to click + and ground.

I asked because radxa doesnt has this component for one of the mini boards they designed… But yeah thats what I did and I posted here the results here.

Im using the waveshare nano board… radxa doesnt has something alike… thats why but… yeah… that work around is fine.
