The sharp pogo pins would sink into the soft solder so no need to remove the Bluetooth wires. If the solder is not that soft, locating holes could be made by any method.
? I want to buy but everything is sold in ebay store when will be available new quantities
It's nice to know that someone is listening to ideas for improving their products. Well done.
Stop wiggling, you'll go blind.
Hi Julian, thank you for the videos. Have you seen the AVHzY CT range ? I'm currently (no pun intended) trying to find the best one and just can't shift the wheat from the chaff
I watch each of your videos.
I like your videos very much.
Your videos are very informative.
Please make a video tutorial for stm8s (As they are very cheap) microcontrollers with st-link v2.
These should be easier to upgrade.
Where the heck can I get info about the features of the various iterations of these devices? I can't even find a website for the so-called "YZXStudio".
I just used the ghetto method of connecting female-to-male Dupont wires and holding the male pins against the pads!
hey julian, would you mind if you share the red firmware? I contacted the seller and hes not replying because the listing says hes away. I want to update this firmware since I have everything already and even backed up the original firmware.
Ingenious way to hold the pogo-pin programming adapter! And these monitors are indeed interesting devices, thanks for so comprehensive review videos.
I think the extra chip in the yellow one won't be a FET, it probably be a simple 2 channel DAC to set the data pin volages, similar to the function of smart USB charging chips.
