It's just a week since I was laying out two new Nanode pcbs - and the first of them has just been delivered.
Here's the new Nanode RF - almost built but without the RFM12B module soldered yet - because someone forgot to bring them back from work!
It has already run Blink and the Pachube Analogue Sensor Sketch - so I have confidence that the ethernet operation is just as it should be.
Note the new green LED added and the smaller footprint of a mini B USB socket - yet to be added.
The RFM12B module sits in the bottom left corner next to the voltage regulator - yet to be added - after the RFM12B is in place.
A group of four boards showing the topside and underside.
Underside of the pcb showing several new components - notably the micro SD socket and the Real Time clock and crystal underneath the ATmega microcontroller.
Above - the topside of the pcb shows one or two new component footprints - most notably the pads for the surface mount RFM12B module in the bottom left corner. The Hackerspace logo now accepts an 8 pin DIL socket for an optonal expansion memory device.
Here is the new prototype Nanode RF - just like Nanode 5, but with lots of new features:
1. A Hope RF RFM12B transceiver for 2 way communications with other boards.
2. A microSD card for general datalogging storage, storing applications and webpages
3. A realtime clock IC with alarm function which also holds a unique ID - or MAC address
4. 3V3 operation - but retains 5V compatibilty for use with Arduino shields.
5. An 8 pin socket (under the H logo) to allow you to add non volatile RAM for program download
6. An 8 pin SOIC footprint to accept an alternative memory device - instead of micro SD card
7. mini B USB connector for powering at 5V
8. Four - better spaced mounting holes.
9. Fully sealed vias for better soldering - less chance of solder shorts
10.Improved screenprint for better identification of connections.
11. Extra LED - for monitoring RF activity - or whatever.
12 Super capacitor for maintaining SRAM and RTC non-volatility.
Nanode RF has been produced in association with Megni/Open Energy Monitor - and the first sampled will be deployed as basestations for their EmonTx wireless energy monitor and wireless graphic LCD product.
Nanode RF, although debuting this week at the OSHcamp and Homecamp4 will not be on general sale or volume production until the New Year. This will allow time to port firmware across to these boards and develop applications.
It is anticipated that Nanode RF will be available in 2012 for about £30 - depending on the hardware options fitted.
