Now you’re ready to connect CHIP to a screen, keyboard and mouse or even work on CHIP from another computer. Also, our delightful little Power Management IC, the AXP209, handles pass-through power, so while on and charging a battery, CHIP is basically running on a un-interruped power supply – If charge power fails, CHIP seamlessly switches onto battery power without shutting off. Roughly, it takes about four to six hours to charge a 3000 mAh LiPo battery from a 5V 2A power source. What’s really great is that if you plug in to a charger and plug in a battery, the battery will charge - all the power management is on CHIP itself. If you have added a connector to your own battery, make sure you have the JST wired correctly: the (-) connection should be on the outside edge of CHIP. The JST can only plug it in one way: if you are having a hard time lining things up, turn it around! Needless to say, do not force the battery connector into the socket if something doesn’t feel right! Specifically, any single cell (1S) 3.7V Lithium Polymer (LiPo) battery with a 2-pin JST-PH 2.0mm end can be connected to the JST-PH socket. This CHIP is using the power from a computer’s USB port:ĬHIP can also be battery powered. Just plug a USB-A-to-microUSB-B cable (that’s the same cable most phones, tablets, and whatnot use to charge) into the wall-wart and CHIP, and you’ll see the PWR LED light up. We recommend a 5V powersupply with 2 Amps current available. If for some reason you don’t have one, you can buy one at any electronics retailer. USB wall-wart adapters are probably littered all over your house. The CHIP’s microUSB connector is used to provide power from most any USB power source. When CHIP is on, you should see the PWR LED light up nice and bright. There are two LEDs next to the USB micro connector. As a result, many of your senses are not great indicators that it is working. It doesn’t take much energy, so it’s not very hot. This may be more than you need to know if you just want to plug it in to the wall, but, as you build projects with CHIP, you’ll be happy to know there’s a lot of ways to get the electricity flowing. To make sure you have enough headroom, we recommend that you use a 5v power supply with 2 Amps current available (you could go as low as 900mA, but you risk brown-outs). In general, CHIP is powered by a 5-volt source like a USB port or phone charger, and draws about 500mA peak (at boot time), runs on around 200mA, and rests with around 80mA with the processor totally unloaded. This might seem so straightforward that it doesn’t deserve several paragraphs, but CHIP is pretty clever, so there’s actually a few things worth knowing. We’re going to cover how to turn CHIP “on”. The single most important thing to using any electronic device is getting electricity to the right places. Let’s boot CHIP into the CHIP Operating System and do some computer things! Add some power, turn on the wireless network, and even connect a bluetooth keyboard to get rid of those annoying cables. So how do use this thing? Let’s get started. And because it’s based on the popular Linux Debian, if there’s something you need, you can probably install it. The CHIP Operating System is built for doing: browse the ‘net, send email, play video games, listen to music, write a novel, watch a video, or learn programming. In a few seconds, you’ll have CHIP’s operating system on your screen, ready to do computer things.ĬHIP is built for making - we’ve packed a powerful processor, 4 GB of storage, stereo audio, video out, and lots of connections for playing and making your projects and products. Grab an old TV (or any screen with a composite video input), a keyboard and mouse, and stick some electricity in the micro USB port. And every computer needs an operating system.
