Collaborate Disseminate
In today’s episode of Diminutive Device Technology Overview, [Sprite_TM] is at it again – this time conquering the HC32L110. A few weeks ago, we have highlighted the small ARM Cortex …read more Continue reading Heroic Efforts Give Smallest ARM MCU a Breakout, Open Debugger
We’ve been contacted by [Cedric], telling us about the smallest MCU he’s ever seen – Huada HC32L110. For those of us into miniature products, this Cortex-M0+ package packs a punch …read more Continue reading New Part Day: Smallest ARM MCU Uproots Competition, Needs Research
The nRF51 Series SoCs is a family of low power Bluetooth chips from Nordic Semiconductor that is based on ARM Cortex cores. The nRF51822 has the Cortex M0 core and is used in a lot of products. [Loren] has written a blog post in which he claims to be able …read more

There’s a sinking feeling when a firmware upgrade to a piece of equipment goes wrong. We’ve all likely had this happen and bricked a device or two. If we are lucky we can simply reapply the upgrade or revert to a previous version, and if we’re unlucky we have to dive into a serial debug port to save the device from the junk pile. But what happens when both those routes fail? If you are [Arko], you reverse-engineer the device and write your own bootloader for it.
The offending bricked object was a Monoprice MP Mini Delta 3D printer to …read more

As the LoRa low-bandwidth networking technology in license-free spectrum has gained traction on the wave of IoT frenzy, LoRa networks have started to appear in all sorts of unexpected places. Sometimes they are open networks such as The Things Network, other times they are commercially available networks, and then, of course, there are entirely private LoRa installations.
If you are interested in using LoRa on a particular site, it’s an interesting exercise to find out what LoRa traffic already exists, and to that end [Joe Broxson] has put together a useful little device. Hardware wise it’s an Adafruit Cortex M0 …read more
