When we release the first revision of the Mini Ultra Pro, we received some awesome suggestions from our awesome customers. We took the suggestions seriously and incorporate them in this new version of the board!<\/p>\n<p>This is our low power rendition of the Arduino Zero! We hit the limit (program flash, memory) on a custom board based on our beloved\u00a0<a title=\"Mini Ultra 8 MHz\" href=\"http:\/\/www.rocketscream.com\/blog\/product\/mini-ultra-8-mhz-arduino-compatible\/\" target=\"_blank\" rel=\"noopener noreferrer\">Mini Ultra 8 MHz<\/a> board while doing a custom project for a client. As much as we want to make an ATMega2560 version of the Mini Ultra, the chip size (TQFP100) is just awfully too big for our liking and the price is unreasonable for an 8-bit microcontroller. In contrast, the 32-bit ARM Cortex M0+ ATSAMD21G18A provides plenty of processing power and peripherals at a reasonable cost. For the past 10 years, we have been actively involved in wireless sensor network and Mini Ultra Pro is the result of those hours and hours of developing what works in the field. The Mini Ultra Pro works\u00a0great with our updated\u00a0<a href=\"https:\/\/github.com\/rocketscream\/Low-Power\" target=\"_blank\" rel=\"noopener noreferrer\">Arduino compatible low power library<\/a> to allow flexible low power management of the board.\u00a0This version comes <strong>WITH<\/strong>\u00a0the radio transceiver module and <strong>SMA or u.FL<\/strong> assembled.
