Adafruit TPL5110 Low Power Timer Breakout
US$7.63
The Adafruit TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

Adafruit TPL5111 Low Power Timer Breakout
US$9.17
The Adafruit TPL5111 Low Power Reset Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

Adafruit ADXL343 + ADT7410 Sensor FeatherWing
US$18.41
Upgrade any Feather board with motion and precision temperature sensing, with this all-in-one sensing FeatherWing. It sports two fantastic sensors from Analog Devices: an ADXL343 triple-axis accelerometer and an ADT7410 precision temperature sensor. Both sensors are connected over the shared I2C bus, so you can use it with any and all Feathers! We also break out the interrupt pins and address-selection jumpers in case you want multiple Feathers or have I2C address conflicts. We've got both Arduino (C/C++) and CircuitPython libraries available so you can use it with any Feather board and get data readings in under 5 minutes.
