The PICO1TRC is a physical computing board that is compatible with the
Arduino software environment. The board size is 2.1" x 1.65".
All I/O pins from the ATmega328 are
brought out on 2 rows of 14 pins (300mil spacing). See the
PICO1TRC datasheet
for the
assembly instructions, schematic and bill-of-materials.
Features
- 2.1" x 1.65"
- Replaceable and upgradeable CPU (ATmega168 or ATmega328)
- Compatible with the Arduino development tools.
- Adjustable Linear Regulator (Vcc 3.3V - 5V)
Output voltage is set by changing one resistor.
Resistors for 3.3V and 5V are included.
- RTC Features
- Real-Time Clock (RTC) counts Seconds,
Minutes, Hours, Day, Date, Month, and Year
with Leap-Year Compensation Valid Up to
2100
- Two Time-of-Day Alarms
- Programmable Square-Wave Output
- Backup power from a CR1220 coin cell.
- I2C Serial Interface
- Two rows of 14 pins (300mil spacing) with all ATmega168/328 I/O functions.
- Six pin header for an FTDI TTL-232R-3V3 cable.
- Debug LED that can be jumpered to Pin 7 or disconnected.
- A/D reference supply filtered per Atmel specification.
- Reset circuit per Atmel specification.
