ATTiny 25/45/85 8SOIC LED Toy Control Simple. V1.2

2 layer board of 0.50x1.00 inches (12.70x25.43 mm).

1. Uses an ATTiny 25/45/85 8SOIC to control common LEDs (WS2801 or APA102).
2. Reset button advances sequence in code, with pins included for additional remote reset button.
3. Program with 8SOIC Test clip, there are no ICSP pads.
4. This is very small.
5. Works just fine 3.3V and 5V. One Li-Ion battery is perfect.
6. I am using these in various projects. With a 20 mhz resonator they can do some impressive POV effects in flow toys (poi/staff).

MPU6500 6-axis motion sensor plus AK8963C magnetometer plus BMP280 pressure sensor with the SENtral EM7180 sensor fusion hub with M24512DFC EEPROM to store the SENtral configuration file. SENtral takes 9-axis accel/gyro/mag data from MPU6500 and AK8963C and performs hardware sensor fusion returning raw data, quaternions, linear acceleration, and heading, etc. Breakout board using the SENtral with jumpers to take power from edge pins for breadboard use or to mount directly on the Teensy 3.1 for comparison between open-source software sensor fusion and the hardware sensor fusion provided by the SENtral. SENtral can act as master to BMP280 pressure sensor and in the future include the pressure data in the sensor fusion.
