Not only can it do the work of two multimeters, but it can do it with amazing precision and flexibility. With it you can measure high or low side DC current, the bus voltage, and have it automatically calculate the power. It can do so over impressive voltage, current, and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.\u003c\/p\u003e\n\u003cp\u003eWorks great with any microcontroller that is CircuitPython or Arduino compatible as well as single board computers such as the Raspberry Pi. It is compatible with 3V or 5V logic and can measure bus voltages up to +36VDC. Not for use with AC voltages.\u003c\/p\u003e\n\u003cp\u003eMost current-measuring devices operate with some notable constraints that limit what they can be used for. Many are low-side only which can cause issues as the ground reference changes with current. Others like its little sister the INA219B avoid this by measuring on the high side but need to change their shunt resistor to measure different current ranges. The INA260 avoids these limitations, and with it's integrated precision shunt resistor it can be used to measure as much as \u003cstrong\u003e+36V\u003c\/strong\u003e at up to \u003cstrong\u003e15A Continuous\u003c\/strong\u003e on either the \u003cem\u003ehigh or low side\u003c\/em\u003e.

It's powered by our new favoritest-chip-in-the-world, the SAMD51, a Cortex M4 core running at 120 MHz. This chip has a speedy core with CircuitPython and Arduino support, hardware DSP\/floating point, dual DACs (more on that later!) and all the goodies you expect from normal chips like I2C, ADC, DMA, etc. It has a roomy 512KB of flash and 192KB of SRAM so it's great for CircuitPython, we added a full 8MB flash chip so tons of space for files and audio clips. Or you can load Arduino in for bonkers-fast audio processing\/generation with our fork of the PJRC Audio library.\u003c\/p\u003e\n\u003cp\u003eThe native USB port can turn it into a MIDI USB device if you like, in both Arduino and CircuitPython. Tether it to a computer or tablet, if you like. Or use it in standalone mode, as long as its powered from a USB power plug, it'll run whatever firmware is burned into it.\u003c\/p\u003e\n\u003cp\u003eOK so you've got this big brain, but now you need inputs and outputs! There's a 4x8 grid of elastomer button pads with a NeoPixel nestled in the center of each one. You can read any\/all button presses simultaneously thanks to the fully diode'd matrix, and also set each button color to any of 24-bit colors. (We've even got some DMA Arduino code for the NeoPixels so that they won't take up any processor time.) The elastomer buttons are translucent so they glow beautifully when lit.\u003c\/p\u003e\n\u003cp\u003eTime to make some noise! We picked the SAMD51 mostly because its got that dual DAC - that's two 12-bit, 500KSPS 'true analog' outputs and we connected them to left and right on a standard headphone jack. Since the DAC pins are also ADC pins you could also use the left\/right for audio line level \u003cem\u003einput \u003c\/em\u003eif you so choose. You're not going to get audiophile-quality outputs from two 12-bit DACs but you can certainly play audio clips and make beeps and bloops.\u003c\/p\u003e\n\u003cp\u003eAnd if you want to have some audio inputs, we have you covered. The 4th pin on the headphone jack is for microphone or line in. If you have a classic 'mobile phone headset', the electret mic will go through an amplifier into an ADC pin. Again, it's not audiophile quality (we're talking about an electret mic here) but you can do audio recording and filtering on the mono input. The raw un-amplified mic input is also connected to a DAC so you can read button presses on headsets that have a resistor-selector for their buttons, or some other 3.3V-max analog signal.\u003c\/p\u003e\n\u003cp\u003eTo add more interactivity, a precision triple-axis accelerometer from Analog Devices, the ADXL343, is included as well, and provides sensor information on tilt, motion, or tapping. Great for adding another dimension of data input in addition to the button pads.\u003c\/p\u003e\n\u003cp\u003eFinally, a 4 pin JST hacking port is available for extra add-ons. It's STEMMA and Grove compatible \u003cstrong\u003e(NOT STEMMA QT!)\u003c\/strong\u003e, and provides GND, 3.3V power, and two pins that can be used for I2C, ADC, or a UART. So connect some other sensor, or read stereo audio in, or maybe hack together a MIDI port.
