Protocols

AT commands control and configure single point firmware.

Standard multipoint firmware uses a simple packet based protocol

and requires a host to enable the module to function effectively.

Single point only allows a point-to-point connection, whereas

multipoint allows more than one simultaneous connection.

GPIO

9 x digital

2 x analogue (8 bit resolution)

Indicators

1 x programmable LED (small form factor board only)

Lead free

Lead free and RoHS compliant.
