Please, consider that this sale is for a bare BetaBrd PCB without any components or pin headers. If you would like a kit with the components, please contact me. In the course of the last few months, I built and worked with this flexible breakout board in order to test the ATtiny84A, ATtiny44A and ATtiny24A capabilities in a mesh network. It performed very well and satisfied the needs completely. Now, I would like to offer you the chance to use the BetaBrd in your own projects. The BetaBrd is deisgned to be put on a breadboard and used with an external power supply (5V, 3.3V or any other voltage supported by the ATtiny). It has an LED indicator (D1) tied to pin B2, a place for a quartz crystal (up to 20MHz), a reset button, a robust reset circuit built according to Atmel recommendations and several onboard jumpers for configuration. The board can be used with or without the quartz crystal (without the quartz crystal, you gain two additional IO pins but you cannot run the board at frequencies above the 8 MHz of the internal RC oscillator). The BetaBrd provides access to all ATtiny pins via two pin header strips and has an additional standard 6-pin ISP header for programming and/or power provision. The board and the ATtiny microcontrollers are compatible with the usual programming toolchains. In my project, I used USBasp programmers and Avrdude to program the board and, in some cases, to power it via the ISP header. What I was interested in, was the creation of a mesh network on the basis of the Nordic Semiconductor nRF24L01+ radio transmitters. While I do not use the Arduino platform in my daily activities, I ran successfully several Arduino projects on BetaBrd. The board played very nicely with the Arduino libraries. For the purpose, I used the arduino-tiny project at http://code.google.com/p/arduino-tiny/ and tested on ATtiny84A and ATtiny44A. The BetaBrd performed very well in my tests spanning several months. I designed it using the latest stable version of the open-source EDA software KiCad. In the last attached picture, you can see the KiCad schematic of the prototype of the BetaBrd. The board was manufactured locally in Bulgaria (EU) and has an ENIG (Nickel/Gold) lead-free finish. More information about the board can be found at: http://www.ilchev.net/betabrd As always, this is a private auction without any guarantees.
