measure the power consumption of the ATmega3208 and other peripherals on the board, de-solder the 0Ω resistor
and connect an ammeter over the Current sense footprint.
Figure 3-4. Current sense footprint
Tip: A 100-mil pin header can be soldered into the Current sense (J301) footprint for easy connection of
an ammeter. Once the ammeter is not needed anymore, place a jumper cap on the pin header.

3.5.1 ATmega3208
Microchip ATmega3208 is a microcontroller featuring the AVR
20 MHz and with 32 KB Flash, 4 KB SRAM, and 256 bytes of electrically erasable programmable read-only memory
(EEPROM) in a 28- or 32-pin package. It uses the latest Core Independent Peripherals (CIPs) with low-power
features, including Event System, accurate analog features, and advanced peripherals.
