The MiKro – An Arduino UNO form factor based board using the ATmega 1284p micro controller

Hello everyone, some people have noticed on twitter that I was trying to compile the optiboot boot loader for the ATmega 1284p for the 5V/16MHz configuration. I finally succeeded and created the MiKro board which is described in a little more detail on it’s dedicated project page: Although the the MiKro is work in progress […]

Firmware v1.1.0 available for the BLE-Shield v1.0.0

Hello everyone, I already published the new firmware v1.1.0 for the BLE-Shield v1.0.0 to my github repository which is available through this link: In this firmware I omitted the internal 16 byte buffer so the shield now acts better as a serial bridge as before. I removed the control characteristics to query the content of […]

BGLib on the BLE-Shield v1.0.0

Hello everyone, I should have done this earlier, but good things need some time. As you might know, Jeff Rowberg @SectorFej as a BGLib Implementation created and published on github: which runs on Arduino. You need a special firmware for the BLE112 module to be flashed which is available on his github repository as well. The BLE112 […]

A whole family of BLE devices. The BLEbee, the BLE-Shield v2.0.0 and the early version of the BLE-Duino 32u4

Hello everyone, this time I have a pile of news for you. Since the development of the BLE-Shield and the initial prototype of the BLEbee, I did some more research and prototyping on three new BLE enabled boards: BLE-Shield v2.0.0 (need another iteration before a private beta test) BLEbee v1.0.0 (almost ready for a private […]

Preview of the K-Duino

Hello everyone, initially I was planning to use the ATmega2560, similar to the setup used on Sparkfun’s Mega Pro 3.3V to create an Arduino Clone of my own. I played around with an ATmega644p some months ago before I created the BLE-Shield but I stopped working on it due to the lack of spare time invested […]
