IoT Devices Launches Low-Power Arduino-Compatible ATmega1284P LoRa Node Board
This $15 gadget boasts better specs than its ATmega328P equivalents, and comes with an on-board watchdog timer for ultra-low power sleep.
Swiss Internet of Things (IoT) specialist IoT Devices has launched a low-power, low-cost Arduino-compatible LoRa node built around the Microchip ATmega1284P — an upgrade over the ATmega328P-based rivals it aims to replace.
"This is a perfect replacement board for ATmega328P projects with LoRa," IoT Devices claims of its latest creation. "The ATmega1284P offers 128kB flash and 16kB RAM while maintaining the easy of use of the ATmega328P based boards. Most sketches can be used with only minor or no changes."
The Arduino-compatible board uses an RFM95 radio module — which is left up to the buyer to buy and solder into place — to offer LoRa long-range low-power wireless connectivity. Its creator claims the node offers impressively low power consumption, thanks to the inclusion of a Texas Instruments TPL5010 watchdog timer in the design — down to 0.56μA while waiting for wakeup.
The board supports wire, helical, or SMA-connected antennas, features a voltage divider, I2C, and 1-Wire pull-ups, an interrupt pin with pull-up resistor, a TPS782 500nA regulator, and room for a reset button — though this has to be requested at the time of order as an add-on.
The LoRa node is available to order via IoT Devices' Tindie store at $15.
