SAM 15×15 is a Tiny Arduino Zero Compatible Board based on Atmel SAMD21G18 MCU

Arduino Zero is an official Arduino board based on UNO r3 form factor but using Atmel SAMD21G18 ARM Cortex M0+ MCU instead of an AVR MCU. Albert van Dalen has decided to design a compatible module based on the same MCU, and called SAM 15×15, as its size can be trimmed down to as low as 15×15 mm. SAM 15×15 comparison with Arduino Zero and Uno boards.

NXP LPC Microcontrollers Roadmap for 2017 – LPC800 and LPC54000 Series

With the acquisition of Freescale, NXP now has both Kinetis and LPC ARM Cortex M micro-controller families. The company has kept selling both so far, but it’s unclear whether they’ll keep developing new Kinetis MCU family in the future. There’s no such doubt about LPC family with the company having published a 2017 roadmap for ARM Cortex M0+ based LPC 800 series, and ARM Cortex M4 based LPC54000 series. LPC800 series MCUs are promoted as 8-bit MCU alternatives, and three new models are expected next year: LPC84x ARM Cortex M0+ @ 30 MHz with 64KB flash, 8 to 16KB RAM available in QFN and LQFP packages. LPC802 ARM Cortex M0+ @ 15 MHz with 16KB flash, 2KB RAM available in TSSOP packages LPC804 ARM Cortex M0+ @ 15 MHz with 32KB flash, 4KB RAM available in QFN or TSSOP packages There will be new models of the more powerful LPC54000 […]

Get Cypress PSoC 4 MCUs for $1 Delivered to Your Door by Fedex

How many times have you found a low cost MCU, or a development kit, ready to order, until shipping fees, sometimes several times the price of the item, curbed your enthusiasm, to the point you just decided to cancel your purchase? It happened to me several times, so I was pleased to find out Cypress Semiconductor will ship their PSoC 4 MCUs via Fedex anywhere in the world without actually charging for shipping. PSoC 4 are ARM Cortex M0 MCUs with up to 32 kB Flash, up to 4 kB SRAM, and analog and digital I/Os. CY8CKIT-042 PSoC 4 Pionner Kit is the corresponding kit development kit, which happened to be voted product of the year 2013 on Element14 community beating the BeagleBone Black, Freescale SABRELite, and PiFace Digital for the Raspberry Pi. Development can be performed using PSoC Creator, and there seems to be a developer community active enough to provide 100 projects in 100 days. So […]
