Engineer and developer Alex Tan based in Singapore has launched a new Kickstarter crowdfunding campaign for the SAMD21 M0+ Arduino-compatible board. Featuring a 32-bit 48MHz ARM Cortex M0+ w/ internal 32K Ram 256K Flash, 8M Ram 128M Flash onboard and more.
“I have sourced and used many microcontroller boards for many projects and very often I find boards with insufficient pins, too big, too power hungry, and require additional time to customise to my project needs. I needed a board with more functions, versatility and ease of customisation. I figured, lets build a board and share it out to fellow engineer who may encounter the same problem…”
