The PICO1TRCL 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).
There is an SMD kit (bottom right picture) and a TH kit (top right
picture). The LDO regulator in the SMD version is in a SOT23-5
package and has an Iq of 900nA. The LDO regulator in the TH kit is an
DIP-8 package and has an Iq of 15uA. The PCB is the same for both
kits.
Features
- 2.1" x 1.65"
- Replaceable and upgradeable CPU (ATmega168 or ATmega328)
- Compatible with the Arduino development tools.
- Dual output voltage LDO -- 3.3V/2.2V
- Low LDO Iq -- 900nA (SMD), 15uA (TH)
- 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.

Accessories
The FTDI USB to Serial Cable TTL-232R-3V3 is required to program
the PICO1TRC. If the board is configured for 5V operation then either
the 3.3V or 5V FTDI cable will work.
