  • 11:50, 22 August 2020 173.174.136.213 talk posted a new comment on T200 (Ah figured out I had to jump the J48 pins to allow for DC power. Next question: is this charging the batteries while plugged in?)
  • 11:22, 22 August 2020 173.174.136.213 talk posted a new comment on T200 (Hello, any more info on how to make this work? I have 4 batteries which show a half charge, everything plugged in like the photos, with USB control cable and header in, DC power from T200 to Jetson, and main power plugged in also. When pressing power button, the board shows Blue power light, but the jetson nano does not power on. What am I doing wrong?)

  • 19:08, 20 August 2020 47.41.19.7 talk posted a new comment on 2.8 inch Touch Screen for Pi zero (I think I am having the same problem. The screen is connected, and is obviously receiving power. But the screen itself just doesn't show anything! I followed their driver instructions, and after reboots, it simply doesn't do anything beside turn on the backlight.)

  • 01:46, 19 August 2020 107.184.50.252 talk posted a new comment on X735 (I have the x735 v2.1 working on a pi 4B and I am trying to use the x735 as a power management. Since Pi requires 5V 3A and my monitor requires 5V 2A, I want to provide 5V 6A (fast charging cable) to X735 using USB C, and it provides power to pi though 40 pin and provide power to monitor though 5V out on x735. Does this work? I try to use the usb C for my power supply.)

I can confirm this is working with this board, however i get Kernel Messages about UAS mode. After applying usb.quirk as describerd here (https://www.raspberrypi.org/forums/viewtopic.php?t=245931) there are no errors anymore. How well is UAS mode implented in youre device?)

I'm surprised to see that "5V OUT" XH connector does not provide 5V to power an additional fan. Is there any particular setting i'm missing ?)

  • 05:46, 9 August 2020 109.171.137.229 talk posted a new comment on 2.8 inch Touch Screen for Pi zero (@jdeFalconr: Any luck troubleshooting this issue? I'm attempting to use the MZP280V04TR V1.0 model screen with a raspberry pi zero w. I've followed the Read.me instructions for installing the device drivers. Once I 'sudo reboot' the screen backlight turns on, but there is no image displayed (i.e., no raspbian desktop). I haven't found any additional information online to help me troubleshoot this issue. Has anyone been able to get this screen working?)

  • 23:24, 5 August 2020 77.8.144.68 talk posted a new comment on X400 V3.0 (Important information missing as well: The power switch simply cut the power to the whole system. there is no proper shutdown of the raspberry, it is like removing the plug. To turn off the raspberry in a clean way when pressing the button, I made a small circuitry with a relay that latches the poser supply and sends a power interrupt to the pi to turn it off when the button is pressed. The relay opens the power to the board once the rpi has shut. There are some out-of-the-box shields on inte...)
  • 23:14, 5 August 2020 77.8.144.68 talk posted a new comment on X400 V3.0 (There is an error on the power switch connector. Pin 3 is not GND but the voltage of the power supply. (for example in my case I supply 12Vdc -> the pin is at 12Vdc). That Voltage is also the one supplied on the Speaker and power terminal (it is always supplied, also when the system is off by power switch))

  • 04:17, 27 July 2020 Pmsr talk contribs posted a new comment on X728-Software (Managed to get my new x728 going. Solid hardware. But am getting the following output from x728bat.py. What does the Voltage at 4.21V mean? It's far from the 3.7V nominal from the batteries, and from the 5V required for the Raspberry Pi. And 103% for the capacity? The script expects 100 to print "Battery FULL", so there is a fix in need here. ****************** Voltage: 4.21V Battery: 103% ******************)

  • 06:16, 23 July 2020 Abarrow talk contribs posted a new comment on X710 (Great board. One little convenience is that if you have something in the same enclosure that needs to share the input voltage (in my case, it's a 12V USB hub) you can use the other input voltage connector - it's parallel with the power socket, and is NOT switched.)
