Product description

IMPORTANT ADVICE: If you haven't used an RFu before, and want to go prototyping, you will find it very useful to have one of these RFu developer board

The RFu-328 BARE offers all the convenience of the RFu-328 and allows you to add your own radio unit in place of the SRF which is supplied with the standard RFu-328. It was created to support those of you who want to use a Hope RFM-12B unit instead of our SRF for instance. You will see the RFu appearing in other peoples products too like the Open Energy metering solutions http://openenergymonitor.org/emon/

Please note that if you want to add an SRF yourself, you need to chose the CC1110 based unit. If you want our SRF on board, we recommend you buy the RFu-328, saving you a lot of trouble soldering.

For a detailed product description, please refer to the RFu-328.

  • Bulk discounts:  Buy over 10 for £3.53, over 100 £3.13 and over 1000 £2.74 (prices are ex VAT)
