Intel Galileo - Gen 2 - Differences
This is a list of what is different on the Gen 2 board.
Nothing basic, but many details.
- 6 pin serial rather than 3.4 mm jack
- serial at 3.3 volt levels rather than +-12 volts
- 7-15 volt power rather than 5 volt regulated
- can be powered from a shield, via the VIN pin on the Arduino shield header.
Input voltage must be in the range 7-15VDC.
- 12 bit PWM
- supports 12 volt POE capable (needs optional module)
- The Galileo Gen 2 uses a Texas Instruments ADC108S102 ADC (10 bit), which allows for a 4x increase in ADC sampling speed.
- 12 of the 20 Arduino shield pins are connected directly to the Quark X1000 SoC to allow significantly faster GPIO performance on those pins.
- Galileo Gen 2 employs an NXP PCA9685 PWM driver IC with 12-bit resolution, allowing for more fine-grained control on the PWM duty cycle.
- The USB Host port connector now has a full-size Type-A receptacle.
- Board is longer (now 124mm)
