“Really good and easy to install, good to know it has protection against plugging in the battery backwards. My only issue is that the button is too low profile as it doesn't match how far the usb port sticks out, meaning once I've put it in a housing, I can't press the button without using something to poke it. In a V2 I'd love to see some pads or holes for attaching wires for your own power button, and maybe status LEDs. Really solid product tho, will be buying more”
“The shim itself is great, but the documentation, not so good. I am using this in a project that uses a Tiny2040 due to the shim's tiny size, but I had to compare the shim to a normal RPi Pico to figure out what all the pins on it do instead of being able to look at an image or document that tells me what each pin does.
For anyone else in my position, I found that pins 1 and 2 control charging and discharging. When bridged together, this shim automatically knows when to provide power and when to charge the battery. Pin 3 is ground. 3 other ground pins correspond with the ground pins on the normal RPi Pico. All the other pins appear to do nothing (which is good).
I like this shim but it would have been nice if there was better documentation so I could have just hooked it up without wondering if I'm about to fry it.”
“Get these when you can!
After ordering a couple of Pico's a few weeks ago I was sad to read that these shims were out of stock. After dutifully signing up for the back in stock notification I was pleased when the email came through.
I ordered 2 of these LiPo shims and they arrived in next to no time. The shims are of great build quality and are perfect for connecting your LiPo's to your Pi Pico's.
The overall service of Pimoroni has been faultless and I will continue to use them for all my Pi needs.”
