10. Hardware modifications
Besides the factory-default RaspBee configuration it is also possible to modify the hardware
to enhance its functionality.
10.1. Assemble the service header
The service interface provides the microcontroller programming interface of the radio
module. It is useful to assemble a 50 mil 10-pin header on the top side to ensure a proper
connection. We recommend the use of the listed header:
•
MOUSER ELECTRONICS order number: 855-M50-3500542
•
FARNELL order number: 1022305
•
DIGI-KEY order number: 952-1383-ND

The pin description can be found in
Section 9
in
Table 11
. A detailed description of suitable
programmers and related software tools are listed in

Note:
Improper handling in respect of erasing or overwriting the MCU internal flash
or EEPROM completely or in parts may result in an unusable RaspBee unit.
Modification of the pre-allocated EEPROM memory sections or removal of the
pre-installed bootloader will irreversibly preclude restoring, booting or
