T-Board 8 Simple microcontroller prototyping
The T-Board is a breadboard-friendly PCB hosting a microcontroller and its supporting components, offering developers flexibility that the fixed-design Arduino-style boards don't. The T-Board comes in three flavors, each suitable for a different microcontroller:
- 130581-92 / T-Board 8 supports the 8-pin ATtiny25,-45,-85
The T-Board was designed to allow for simple and fast microcontroller prototyping on a breadboard and reduce the number of needed jumper wires, which is supported by the T-Board's integrated 3.3V and 5V-selectable power supply. Programming the microcontroller can be done in-circuit (ICSP).

I purchased these boards to help in moving beyond using a full Arduino board in places where an ATtiny MCU might be sufficient. I particularly like the T-Board 8 since the 8 pin Attiny’s can help reduce parts count in many cases. The T-Boards provide a great platform for bread-boarding and testing your software before wiring up a board. I use WinAVR ide and a USBtinyISP programmer from Adafruit to develop the systems I need. For example, an ATtiny 45, a thermistor, a resistor, and a mosfet were all the parts needed to control a 12V cooling fan for a power supply I’m building. The MCU reads the temperature inside the enclosure and sets the fan speed accordingly. This only required two pins plus a few lines of code. Since I had some extra pins, I decided to add a red/green LED with appropriate resistors to the front panel to give a visual indication of the temperature inside the instrument case. This increased the parts count to eight. I then built the circuit on a small piece of strip board about .75” by 1.5” for installation in the power supply case. The T-Board made the whole process much simpler by cutting down on the number of individual wires normally required when using bread-boards.
