WIRELESS CONNECTIVITY & SENSORS

User manual Setebos-I

6 Host connection

The Setebos-I is intended to be used as a radio module in a system, interfaced with a host
micro-controller. The use of industry standard UART as the primary interface ensures a very
minimal requirement set on the host MCU. As a result of this, the module can be designed in
with most host controllers from a 8051 to the more advanced ARM core architecture.
