Revison 5.0 - Instead of using separate ZIF sockets, use a ridiculous 6P4T mechanical switch to select which lines go to which pins. Supports programming any AVR via the ISP connector, and the following via the onboard ZIF socket:

• ATTiny 25/45/85
• ATTiny 24/44/84
• ATTiny 2313/4313
• ATMega 328P

Breakout board for Texas Instruments' eight-channel I2C multplexer allowing eight separate I2C devices to be controlled by a single host I2C bus. The breakout board accepts VIN from 1.65 to 5.5 V, the I2C lines all have 4K7 pull-up resistors, it has an active low reset (not broken out here but accessible via the resistor solder pad). The TCA9548A can have one of eight addresses so, in principle, up to eight of these boards could be ganged to control 64 separate I2C devices with one master I2C bus. This is particularly useful when using multiples of the same I2C sensor such as motion sensors or environmental sensors where the sensor device has a very limited (usually 2) range of I2C addresses. Added solder jumper to access two of the TCA9548A addresses so up to 16 I2C devices with the same I2C address can be managed with a single host I2C master bus using two of these boards.

Picobot v1.1

Voltage regulator board. This board can supply 3.3V and 5V simultaneously to a circuit mounted on a breadboard. The rails are fully configurable.

Replaces the circuit board of a “Gamecube Style” replacement stick. Complete project details: http://www.maltepoeggel.de/?site=n64stick&lang=en This board is 100% compatible with micros Firmware.

Breaks out any SOIC-14 package to 0.1" headers spaced 0.4" apart, taking up as little breadboard space as possible.

LSM9DS0 9-axis motion sensor plus LPS25H pressure sensor with the SENtral EM7180 sensor fusion hub with M24512DFM EEPROM to store the SENtral configuration file. SENtral takes 9-axis accel/gyro/mag from LSM9DS0 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 LPS25H pressure sensor and in the future include the pressure data in the sensor fusion.
