16. Differences from previous modules

The BISM2 has been designed to be a drop in replacement for previous BISM modules from TDK

Systems and Ezurio. However, some additional features have been made. This section lists all of

these changes. More details can be found in the relevant section of the data sheet.

Significant additions have been made to the AT command set.

Pin 27 is now marked as RESERVED instead of VCC_3V3. It can no longer be relied to provide a 3.3v

regulated output.

Pins 33, 35 & 37 are now GPIO instead of N/C. The default state is configured as an inputs.

Pin 39 is now allocated as GPIO9 which defaults as an input line instead of a “VCC_1V8” monitor.

This change has been made to increase the I/O capability and to prevent noise being injected onto

the 1V8 rail.

The module is physically smaller so the fixing holes no longer align with those of the previous

module.

A brown-out circuit is now incorporated on the module. Reset functionality remains the same.

The Oscillator output is now available.
