and this here is my first solder. Ok I use 1mm of solder with 2% flux. I solder before but this is my first on a circuit board. instead of getting 2x40 pins, i just get a single row of 20 pin in hopes to put on row down first and tack that down and do the second.
And after finding the right spacers to stack it all, here what it came out to be
The Remote Pi board isn’t tack down, because with the new headers on the HiFiBerry the holes don’t match up might have to build a better stand for the screen
if i look at your soldering it could be that row 7 is maybe joint but image is a bit blurry
and i think that’s normal because your pi-remote hat was made based on the first rows of pins…
and if you have 2x 20 pins is better to solder but always check what pins your using because it
could be flipped.
Everything works, power and the remotePi board button lit up, so i know that works.
Next, is the remote control. the remote pi plug is installed on the Volumio. I went over to the hifiberry site to look for the justboom ir remote and they were sold out. so do anyone know of a usb remote plugin to the usb port that works the Volumio.
you don’t need the remote any will do for you because of your pi-remote board you only have to
program it…( as long it’s a ir remote… ) but the usb and remote is mostly on 2.4 ghz and isn’t a real ir ( infra red ) the 2.4ghz will work from every where instead of ir you have to aim to the ir reciever.
Ok, i had been looking into my raspberry pi 4 media player and volumio player today.
Ok, I connected a usb-c cable to the pi 4 (which the remote Pi board has) with my media player on it and used the button on the remotepi board and also on my usb remote and it powers on and off. https://www.amazon.com/gp/product/B07TYQRXTK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 this power cord and still when pushing the button it also powers on/off.
Ok, on my 2 pi 4 with Volumio on it, a usb-c cable won’t work too weak. I connected the power cord https://www.amazon.com/gp/product/B07TYQRXTK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 to it and pushed to button on the remotePi board and it wouldn’t power it on and off. Plus on the screen shows a yellow lightening bolt in the corner of the screen. Could the lightening bolt symbol mean weak power and could that be why my remotePi board wouldn’t power on/off
i would look if it’s really delivering the amps. i had 2 x 5 amp and it deliverd max 1,5 amp in real…
went back to orginal rpi power supply of 3 amp and it works…
i have the power cord, Output: 5.1v 3.5amp. So when i pluged it in the smartipi connection, Volumio started loading. The yellow lightening bolt symbol appears in the right corner of the screen. Everything is power on once connected the power
I pressed the power button on the RemotePi board and it lit up a second but it down power down the Pi. the led light on the power button is on, that’s good knowing that all the boards, the Pi/ HiFiBerry and the power board getting power but the remote pi board want shut down.
one thing do two add on boards the HiFiBerry and the RemotePi Board makes a deafferents. What is a good power supply that will power that will let me power on/off the pi with the remote pi, since this power supply or even a usb-c cable won’t power.
The LED light is on on the Remote Pi board, so its getting power to it but just won’t power down or up the player
Since you mention the lighting bolt, the voltage has dropped below 4.9VDC. Either you’re exceeding the max USB current, or the PSU is crappy and looses voltage on the USB-C cord.
Also spent some extra time on soldering, as it looks like the temp was too low. When finished make sure to remove all left over residu between the pins. You can use 70% ethanol to do this.
it could even be cold joints but could not check it by the photo’s
i had 5.2v / 5amp and it deliverd a wapping 5 volt /1,5 amp max… with tester
and after weeks they got a new batch old batch was bad and again the same result with it.
took my old 3amp rasp power sup. and what i see no undervoltage and running great…
Same experience with 5.1V/10A PSU.
The issue with me was the peak current on the connected USB DAC. Using a calibrated Fluke-189 in MIN/MAX mode, showed a drop below 4.86V and the biggest surprise, the Pi won’t recover from it. It kept running on 4.86V.
