R41Z Module
For details on the R41Z module, see the Rigado R41Z Data
Sheet (
). The
R41Z
module is an industry leading Bluetooth and Thread pre-certified (pending) module with a wide range
of potential applications.
6.4.1
32.768kHz Oscillator
For RTC and to maintain high accuracy Bluetooth time keeping in low power modes, an external
32.768kHz crystal oscillator is provided. Some applications may not require this external oscillator in
which case a set of jumpers can be used to connect these I/O to the expansion headers. The R41Z
module features programmable capacitors which can be used in place of external capacitors.
However, external capacitors are provided on the R41Z Evaluation Board to simplify firmware
development.
