Reset button? Yes! STEMMA QT \/ Qwiic connector for fast I2C? Indeed. Battery with recharging and on\/off switch? Affirmative.

Use any 3.7V\/4.2V single-cell Lithium battery with a JST 2-PH connector in the correct polarity. The battery will automagically charge with the Pico is plugged into USB, and switch over seamlessly to battery when USB power is removed.\u003c\/p\u003e\n\u003cp\u003eBy default the charge rate is 500mA for use with 500mAh+ sized batteries. You can cut a jumper to reduce the charge rate to 250mA if using 250mAh to 500mAh battery. So you don't have to unplug the battery often, a slide switch is connected to the Pico Enable pin, so you can disable the Pico's 3.3V power supply completely - this is as close as we can get to 'turning off' the Pico.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eAlkaline\/NiMH Battery Pack Support\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eYou can also cut a different jumper to disconnect the charger completely from the battery, which means you can use \u003ca href=\"https:\/\/www.pakronics.com.au\/products\/ADA3287\"\u003e3xAA\u003c\/a\u003e or \u003ca href=\"https:\/\/www.pakronics.com.au\/products\/ADA727\"\u003e3xAAA battery packs\u003c\/a\u003e for alkaline or NiMH battery usage. Of course, you will need an external NiMH charger in that case. \u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eDouble Socket Headers\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThis board has double sockets already soldered on, you can plug in your Pico and 'Bell boards directly in, and get access to a prototyping area underneath \u003cem\u003eas well as\u003c\/em\u003e a second row of socket pins. The second row means you can connect wires just by poking them into the header, either directly to LEDs or buttons or to jumper to a breadboard. So you don't have to look up or count pins, each socket is nicely labeled. There's also 4 mounting holes for easy attachment to an underplate. \u003c\/p\u003e\n\u003cp\u003eThe dual socket headers we use are 'hollow' - that means you \u003cem\u003ecan\u003c\/em\u003e connect through the back if desired. Specifically, you can use \u003ca href=\"https:\/\/www.pakronics.com.au\/products\/ADA5582\"\u003ePico Stacking Headers\u003c\/a\u003e to plug through to some other device that is expecting Pico pins. Also, in theory, if you soldered pin headers on the 'wrong side' of a Pico, you could plug it up through the bottom.\u003c\/p\u003e\n\u003cp\u003eWe recommend picking up a set of \u003ca href=\"https:\/\/www.adafruit.com\/product\/550\"\u003elittle rubber feet\u003c\/a\u003e to protect your desk if you're not mounting this board to something else.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo 2x20 slim socket headers \u003c\/strong\u003e- plug in your Pico and desired 'Bell and have an extra row of sockets for each pin!\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJST PH connector\u003c\/strong\u003e for LiIon\/LiPoly or Alkaline\/NiMH battery usage - be sure to cut the \"disable charge\" jumper to use Alkaline\/NiMH batteries.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiPoly\/LiIon charging circuitry\u003c\/strong\u003e for any 3.7V\/4.2V nominal 1-cell battery.

If using the Philhower Arduino core, the Wire peripheral is already set up to use IO4 and IO5.
