Microcontroller circuit, RF SoC, ADC input, Battery powered

In Progress Posted 4 years ago Paid on delivery
In Progress

Circuit design needed. No PCB layout needed, as the packaging is to be determined.

Components:

- RF module SoC (System on Chip) Sigfox Chip AX-SFAZ

- Microcontroller with In Circuit Debug or similar (open to suggestions )

- SMA connected antenna

- Battery power supply (open to suggestions)

- ADC for either 3.3 or 5v (5v preferred)

- Microcontroller driven LED for feedback

- ADC reading of a sensor on a long wire (1-2 metres)

For power conservation purposes, the circuit will sleep most of the time, with some component of the circuit waking up with some configured time-span (10 seconds for example).

Sensor accuracy is not critical, although read consistency is.

Hello, You specify the AX-SFAZ IC but you attached the data sheet for the AX-SFJK. The ICs, Sigfox zones, and hardware designs are quite different. Which is it? Once I know, I can provide you with a fixed price quote. More
