NB-IoT 2 Unit Global Version (SIM7028) with Antenna Brand_ModMyPi Onboard dual touch circuit

Onboard dual touch circuit

is a small form factor system ideal for enabling the next generation of low-power Machine Learning (ML) devices

not the Raspberry Pi

so it can be used with input voltages as low as a few hundred millivolts above 9 V
