Grove Pro Mini LP

P r o d u c t S p e c i f i c a t i o n
This section is a modified version of the official Arduino Pro Mini documentation modified for low power
operation (the Grove Low Power Pro Mini LP).
Power
The Grove Pro Mini can be powered with an FTDI cable or breakout board connected to its six pin header, or
with a regulated 3.3V or 5V supply on the VDD pin. On the Grove Pro Mini LP, the RAW pin is not
connected. There is no voltage regulator on the board. You must supply regulated 3.3V or 5V to the VDD
pinThe power pins are as follows:
RAW - No Connect
VDD - The regulated 3.3 or 5 volt supply.
GND - Ground pins.
Memory
The ATmega328 has 32 kB of flash memory for storing code (of which 0.5kB is used for the bootloader). It
has 2 kB of SRAM and 1kBs of EEPROM (which can be read and written with the
EEPROM library .
Input and Output
Each of the 14 digital pins on the Grove Pro Mini LP can be used as an input or output, using pinMode ,
digitalWrite , and digitalRead functions. They operate at 3.3 or 5 volts (depending on what VDD is connected
to). Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected
by default) of 20-50 kOhms. In addition, some pins have specialized functions:
Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins
are connected to the TX-0 and RX-1 pins of the six pin header.
External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low
value, a rising or falling edge, or a change in value. See the attachInterrupt function for details.
PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite function.
SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication,
which, although provided by the underlying hardware, is not currently included in the Arduino language.
LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the
LED is on, when the pin is LOW, it's off.
The Grove Pro Mini LP has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different
values). Four of them are on the headers on the edge of the board; two (inputs 4 and 5) on holes in the
interior of the board. The analog inputs measure from ground to VDD. Additionally, some pins have
specialized functionality:
