What is it?
This is a perfect replacement board for Atmega328P projects with Lora. The Atmega1284P offers 128KB flash and 16KB SRAM while maintaining the easy of use of the Atmega328P based boards. Most sketches can be used with only minor or no changes.
What makes it special?
- Arduino compatible & preloaded bootloader (MightyCore)
- Atmega1284P with 128KB flash and 16KB RAM, easy replacement for Atmega328p boards
- Ultra low power consumption, down to 560nA (0.56μA) with TPL5010 as watchdog
- Small form factor, 36.5mm lenght, 31.5mm width
- TPS782 low quiescent 500nA regulator
- RFM95 can be soldered to the bottom side
- Wire antenna, helical antenna, SMA antenna support
- TPL5010 can be used to wakeup the Atmega, with optional watchdog function
- Voltage divider on board, enabled through two MOSFET driven by a pin
- I2C and 1-Wire pullups on board
- Input pin for interrupts with pullup resistor on board
- Two GND pins can be powered on/off through a MOSFET driven by a pin
