After Moteino R4 has been the long running champion of its lineup, and R5 has had a brief period of glory, Moteino has now been shipping for the past week at revision R6!
Wait, what happened to R5 which was never announced you ask?
Well R5 was mainly a transceiver layout change from R4, it also added a u.FL RF connector (which is now offered in the shop) and SMA connector “helper” pads, and few other minor layout changes, nothing too significant and otherwise identical to R4. Customers were now getting HCW and LoRa radios on the same Moteino PCB instead of separate PCBs for HW and LoRa.
However in R6 there are more important changes:
- CW transceiver layout has been added in addition to the RFM69/LoRa layout, which means that the whole spectrum of RFM69 and LoRa radios are supported. Note that W and HW, while still in the shop, are no longer available as an option for MoteinoR6 – they are replaced by CW and HCW (which are 100% equivalent from a software and features perspective, but smaller!)
- supported transceivers: RFM69CW, RFM69HCW, RFM95/96/LoRa
- in addition to this, RFM12B is now also usable (though not sold) with Moteino R6 because of the new CW pads. Note that the RFM12B library is still usable but no longer actively developed or supported
- a delay cap was added to DTR to avoid situations where the Moteino never wakes from an ultra low power state – this has been mentioned and discussed in the forum
- u.FL pads kept for those who want to connect a pigtail instead of straight coax or the provided monopole wire antenna
- the Trace Antenna variant reflects all these changes as well except it’s connected to the onboard PCB antenna and does not require an external antenna
Here are RF connector options now possible on the Moteino, all these RF connectors are available in the shop for convenience:
