HopeRF wireless shield

[DaveChambers]

A HopeRF wireless shield using the following would enable us to put together really small wireless sensor packages: http://jeelabs.com/products/rfm12b-433-mhz !

Yes, this would be really great!

A RFM12 board for TinyLily would also be fantastic. But additional pins would be needed or it must be integrated somehow with the processor board.

That would be incredible...
Dooooo itttttt

this gets my vote.

so just looking at it, an RF22B will not fit on the face area of a tinyduino breakout board. Its too big. you could do it, but just eyeballing it, it looks like it would impinge on the drill holes in the corners. Also, the RF22B is a 3V3 system, and the tinyduino is a 5V system, so you need a level converter, like a 4050, which will need space to mount...

We're working here on a tinyduino breakout board connectorized in molex 53780 that would allow you to connect to a remote board with an RFM69HW. If there is demand we could maybe produce one that would work with an RFM22B...

Anyway, we'll be baking the first batch of boards and testing them in the next few weeks. We'll post the designs and so on once we have tested them and verified they actually work...

I was looking at an RFM69W transceiver I purchased from LowPowerLab and it just fits within the TinyDuino mounting holes (19.6 x 16 mm). I'm pretty confident that creating a TinyDuino shield would be straightforward especially if the longer TinyDuino PCB form factor is used (ala TinyDuino Bluetooth Shield).

Using this RFM69 Breakout Board as a reference from the article Creating a Schematic for a RFM69 Breakout Board, 3 chips (and a bunch of resistors and capacitors) are needed:

1) LDO Regulator MicroChip MCP1703 is 2 x 3 x 0.9mm at $0.68 for 1, $0.47 for 100 (Mouser)
Datasheet: http://ww1.microchip.com/downloads/en/DeviceDoc/22049e.pdf

2) NXP Semiconductors 74LVC245 is 2.5 x 4.5 x 0.5 mm at $0.37 for 1; $0.28 for 100 (Mouser)
Datasheet: http://www.mouser.com/ds/2/302/74LVC_LVCH245A-70410.pdf

3) RFM69W ISM Transciever Module is 19.6 x 16 mm at $6.95 (LowPowerLab)

+1 one from me just what I need.
