Arduino custom board package for Atmega2560

Provides a modified stk500v2 bootloader to support alternate slower (software UART) baudrate programming for pyduino hydrogeologger from the default 1155200 baud for the Atmega2560 chipset.

Supported Chipset

• Atmega2560 (Arduino Mega)

Available Baudrate

• 2400 (Hydrogeologger Default)
• 4800
• 115200 (Arduino Default)

Requirements/Dependencies

Requires an ISP programmer to program bootloader. Some examples...

• AVRISP mk2
• USBTiny ISP
• USBasp

To use a secondary Arduino board as ISP programmer, follow the link https://docs.arduino.cc/built-in-examples/arduino-isp/ArduinoISP#use-arduino-as-isp
