AVR chips have been well-liked for a really very long time as a result of their mixture of low value, environment friendly instruction set, very low energy consumption, and versatile peripherals. Earlier than the sale to Microchip, Atmel had began releasing two new collection of chips – the ATtiny 0- and 1-series. These low-power chips featured new peripherals and had been a fantastic improve path from smaller ATtiny chips. If you wish to take a look at the ATtiny1616, a member of the 1-series, the ATtuno is a good selection.
The board comes with Wago connectors for terribly straightforward wiring of prototypes. Moreover, a 4×4 grid of WS2812 RGB LEDs is included, plus a Stemma QT/Qwiic appropriate port for attaching all kinds of peripherals. Switches are included to vary the ability supply between USB and the UPDI programming port, in addition to change Vcc between 3.3 and 5V.
There’s additionally a barely inexpensive model that doesn’t include the Wago headers; as an alternative, you merely solder in regular 0.1″ headers, which have separate footprints on the board. A number of LEDs present the standing of assorted capabilities on the board, like which voltage is chosen, whether or not the UPDI programming pin is getting used, plus the traditional UART TX/RX LEDs.
All you must get began is a USB cable! It’s not a nasty concept to get your arms on an MPLAB Snap or related programmer that helps UPDI, as having full debug performance might be very helpful.
