[RESOLVED] BOARD POWER ISSUES? try to power the board via CN2 headers

For those of you having power issues I would recommend this.
Make a Barrel Jack adapter and power the board via CN2 headers

The microUSB port can only handle limited current which explains some of the power issues some guys have reported on here. The CN2 pins can handle much more.
Actually, you can use any 5V and GND enabled pins on the board as they are all on the same rail

26 AWG Dupont Wires

DC Barrel Jack Adapter - Female

Take 2 jumpers (Red for VCC and black for GND if you are a purist)
Remove the casing from the male end (or cut off and tin ends with solder if you prefer)
Insert in to Female Jack's screw terminals
Connect female ends to CN2 headers on your LattePanda
Find your favorite barrel connector power supply (I used a 5V@3A one with compatible jack)
Connect and enjoy.
IMG_0604.JPG IMG_0604.JPG (2.03 MiB) Viewed 61006 times Using this setup I was able to power my LP, watch all of season 5 of Breaking Bad off a 2.5" external HDD, powered only by the LP's USB. Actually, I was able to connect 2 external hard drives without issue.
And I left it on over night with heavyload running, which it coped with fine. This was with screen output through HDMI.

Inserting an SD card knocked one of the HDDs out, but this is largely down to the current of my power supply. Using a 4A+ power supply will allow you to use all peripherals on your LP and then some.

Hope this can help someone.
2021-05-07 06:01:35 Hi, I was wondering if support for the Model 1 has been discontinued. I've posted my issue here: https://www.lattepanda.com/topic-f10t31717.html userHeadPic GhostMaster55

Do you get any FTP error messages?
And I have no idea what you are trying to tell us regarding mysql.

I've read your post, and I kinda understand it. My goal was to make my LP portable, an then I need a battery. Yeah, and I found out that you can power the LP through these ports. Since I have to connect a battery, do I have to get an adapter that will help me connect the battery, or do I have to find a 5v battery and plug it directly in to the cn2 port?

Many thanks
Hi there,
We suggest add a voltage stabilization adapter which can output steady 5v voltage to the board.

2018-12-04 12:22:44 ***REPOSTING IN RELEVANT FORUMS (since LattePanda Admin has not replied to PM, and it's been 7-days)

I need to run a VGA connection to my Lattepanda Alpha, but to do so would require using the USB-C port for video output (as stated in your manual). Knowing that I have to use the 12v DC input on the board for power now, and, that I will have other peripherals requiring power (let's say one IDE and one SATA device), what type of SFX/Micro PSU would you recommend I use, so that I have one power source for everything?

This also works great to supply the proper power over USB.

I had power issues with USB and was using the iPad USB charging block and it still did not supply enough power. These items i mentioned above solved the problem.
any portable solution? I thought I've got a beast with 200000 mAh and 3.4 v /2.4 A but it still shuts down randomly.
Please help to post the portable power bank you are using. I know that our team members tested the Xiaomi power bank, which works stable. But it's a Chinese brand. The spec is just 2.1A with standard USB 2.0 port.

Hi, Thanks for your sharing.
May I ask what do you do with LattePanda? As a standard PC or a nice project!

2017-06-17 06:32:19 I followed this guide and my LattePanda started smoking.

Now it no longer boots.

This is very disappointing that guides like exist and are being provided by the manufacture.

I know my LattePanda is not covered by the short 90 day warranty anymore, but is there anything you can do?

What do the green wires do? I was wondering about that as I'm going to use the CM2 Pins as I'm waiting on the US Starter kit to still ship.
don't quite understand what green wires you are referring to, could you clarify?
On your picture there are two other wires connected to your CN2 headers, I was wondering if that's for anything necessary, because my panda keeps crashing on Win10 Setup. I've posted my problem in detail here: viewtopic.php?f=10&t=1084&p=4712#p4712.
