ETRX35x Development Kit
7 Setting up the Hardware
In the development kits are all four versions of the module. They can be powered from either a
USB hub, the mains (via a suitable power supply) or batteries.

8 ETRX35x pinout
The functions of each of the ETRX35x pins depend on the firmware. When using the Telegesis AT
command-based firmware the S-register settings control the configuration of the I/Os. Some of
them have a main function and an alternate function, as determined by the value of register S15.
Holding pad PA5 low when powering up or resetting the module will cause it to enter the
bootloader mode; this operation lies outside the normal firmware so it is independent of the value
of S15. As the functions are firmware-dependent and may change between versions, Table 3
should be read in conjunction with the latest R3xxC AT Command Manual.
Notes on Table 3
Name is the designation of both the ETRX35x pad and the EM35x chip pin.
Index can be used to reference the individual pin in various S-registers (see the R3xx AT
Command Manual)
Pad is the module’s pad numbering
Default direction indicates whether the pad is normally an input or output
Main function and Alternate function indicate the purpose and connection of the pad
Default alt fn setting indicates whether the default firmware setting chooses the main or alternate
function
