Input
(weak pull-up)
Work with M0 to decide 4 working modes of module (not suspended, if not used, grounding).
7
RXD
Input
TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can be configured as
open-drain or pull-up input.
8
TXD
Output
TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as
open-drain or push-pull output.
9
AUX
Output
To indicate module's working status & wakes up the external MCU. During the procedure
of self-check initialization, the pin outputs low level. Can be configured as push-pull output
(suspending is allowed).

Q8. How can we get samples from you ?
A8.Samples are available. Normally we take 2 days to arrange samples. If we have no business record with you before, we need to charge boot samples cost and post courier freight.
Q9.Can your module be connected with Arduino board? Can you provide Sample code?
A9: We don’t know the model of your Arduino, so we don’t sure if our module can be connected with it. Please be sure of the power supply when you connect your Arduino board with our module, 3.3V is ok. But for 5V, you need to add 4-10k pull-up resistor for the TXD&AUX pin. Sorry we don’t have the sample code to offer.
Q10.Can your module be connected with Raspberry Pi?
A10: Yes, our module can be connected with Raspberry Pi.
