3 This is an RF interface board for use with [Arduino](http://arduino.cc)
4 systems. It provides the equivalent of a [TeleDongle](../TeleDongle)
5 plus [Bluetooth](http://www.bluetooth.com), plus a microSD socket for
8 The RF filter components are set for use in the vicinity of 435 Mhz.
10 These are photos of the first prototype:

72 Prototype v0.1 boards will hopefully be working in time to show at the
73 Arduino mini-conference at LCA 2012 in mid-January.
