{"product_id":"pico-lipo-shim","title":"LiPo SHIM for Pico","description":"\u003cp\u003eThis SHIM provides a convenient way of powering your Raspberry Pi Pico from a LiPo\/LiIon battery. You can recharge the battery easily by providing power to the Pico's USB port.\u003c\/p\u003e\n\u003cp\u003eSolder this neat little square to the pins on the back of your Pico, plug in a suitable lithium-ion\/polymer battery and tada - a LiPo Pico! The \u003cstrong\u003einbuilt charging circuit\u003c\/strong\u003e means you can recharge the attached battery by supplying power to the Pico via USB, and it includes \u003cstrong\u003eprotection against overdischarge and overcurrent\u003c\/strong\u003e. There's a \u003cstrong\u003epower button\u003c\/strong\u003e to stop the SHIM from providing battery power when it's not needed and turn your project on and off, as well as two \u003cstrong\u003eLED indicators\u003c\/strong\u003e - a white one that shows when the shim is providing power and a red one to tell you when the battery is being charged.\u003c\/p\u003e\n\u003cp\u003eWe've designed it to be as slimline as possible so it can be sandwiched underneath other add-ons like our \u003ca href=\"\/en-eu\/collections\/pico\" target=\"_blank\"\u003ePico Packs and Bases\u003c\/a\u003e, and it's compatible with any of our \u003ca href=\"\/en-eu\/products\/lipo-battery-pack\" target=\"_blank\"\u003eLiPo\u003c\/a\u003e, \u003ca href=\"\/en-eu\/products\/lithium-ion-battery-pack\" target=\"_blank\"\u003eLiIon\u003c\/a\u003e and \u003ca href=\"\/en-eu\/products\/high-capacity-lithium-ion-battery-pack\" target=\"_blank\"\u003ehigh capacity LiPo\u003c\/a\u003e batteries.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSafety note!\u003c\/strong\u003e You should only use this SHIM with LiPo or LiIon batteries, and you should make sure that any project involving LiPos is sufficiently protected from being dented, bent, punctured or crushed.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMCP73831 charger with 215mA charging current (\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/MCP73831-Family-Data-Sheet-DS20001984H.pdf?v=1618417794\" target=\"_blank\"\u003edatasheet\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003eXB6096I2S battery protector (\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/XB6096I2S.pdf?v=1618418020\" target=\"_blank\"\u003edatasheet\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003ePower button\u003c\/li\u003e\n\u003cli\u003e2-pole JST PH connector, with polarity marked on the board\u003c\/li\u003e\n\u003cli\u003ePower and charging LED indicators\u003c\/li\u003e\n\u003cli\u003eCompatible with Raspberry Pi Pico\/Pico W.\u003c\/li\u003e\n\u003cli\u003eSoldering required.\u003c\/li\u003e\n\u003cli\u003eDimensions: approx 21mm x 21mm x 7mm (L x W x H, including connectors)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/files\/lipo_shim_for_pico_schematic.pdf?v=1618573454\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRaspberry Pi Pico, battery and other Pico add-ons are not included!\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eGetting started\u003c\/h2\u003e\n\u003cp\u003eYou'll need to solder the SHIM to the back of your Pico, with the power button at the same end as the USB port.
