(i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board
after a connection is opened. If a sketch running on the board receives one-time configuration or other data
when it first starts, make sure that the software with which it communicates waits a second after opening the
connection and before sending this data.
Software
Software and drivers for Grove Pro Mini LP boards for the Raspberry Pi and the Arduino can be located on
the SwitchDoc Labs Grove Pro Mini LP product page (www.switchdoc.com). The Pro Mini LP can be
programmed as any Arduino compatible device through the Arduino IDE (select Arduino Pro or Pro Mini from
Board Manager and then ATmega328 (3.3V, 8Mhz). Note you can run the board at 5V, but you must still
choose the 3.3V, 8MHz from the menu. This board runs at 8MHz to reduce current consumption.
I2C Interface
The I2C interface has two sections. J3 and J7 provide Grove I2C connectors (3.3V or 5V) and JP4 provides
a pin header I2C interface.
DS3231/EEPROM Real Time Clock
The SwitchDoc Labs DS3231/EEPROM combination is included with the Grove Pro Mini LP board. It is
plugged in by the user into JP11, taking care to having the battery facing the top of the board.
The DS3231 is a low-cost, extremely accurate I2C real- time clock (RTC) with an integrated temperature-
compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains
