RFM69 breakout boards & a TFT Node

[greginkansas]

No more hand building mega or 5V nodes for me.

Back in stock, they are high but adafruit does release a lot of libs

Seems these boards are handy:




They are meant for ESP8266 modules, but RFM69 fit equally well. Just remove two resistors and ignore lettering...

EDIT:

This is just a break-out board. Distance between the pads is not ideal for RFM69 but it works..
Redirect of the link doesn't work. Copy the link and paste it in your browser.

ct, the proboards redirected link to the connecting plate did not work for me until I pared it down to

The www.adafruit.com board has a 3.3V voltage regulator so you can feed it 5V also a levelshifter
so you can use just this board and a 5V arduino.

It looks like the www.aliexpress.com is just a breakout board. But I'm not sure on this.

Hi All...

These two are great too...if you dont mind too much level shifting with resistors. Good for testing:

There is even one with a nice SMA connector I had ordered. Got 2 sets (6 boards) of the above for $9

Also easy but expensive:

Maybe it can help some people struggling get going faster, or I like they neatness factor they have.

Got 4 boards in and have one on a mega.  I have moved the DI0 pin and now have no pin conflicts so its looking good.

Added the TFT code to a node and it all fits so thats cool. This will push the limits of a single node for sure! TFT writes are SLOW.

With only doing small writes to the tft here and there in the code it working good.

Hi Greginkensas,
What is the advantage of using this module over using the RFM69HW directly?

[greginkansas]

This is for 5V nodes. You can use 5V sensors. My LCD is a mega at 5V

Hi Greg...

Nice LCD node! Can you share the code? Are you using touch?

[jimkernsjr]

Check out this too since you are a fan of the MEGA. You also get a free switchable Bruno LC

May help if you need something compact and to use the MEGA

Yes, using the touch for the 4 btns.

Greg,
Did you have any problems getting the Adafruit RFM69HCW to work on your mega? My attempt is not going so well. My mega gateway locks up after a few minutes with the radio activity light on constantly and it takes a reset to bring it back. Adafruit added a pull up resistor on the reset pin and I'm wondering if this would cause issues.
Thanks!

No issues mine has been up for weeks. Did you fix the ethernet IRQ issue?

Thanks for the reply. That was it. It occurred to me last night that the initial interrupt changes I had made in w5100.h file excluded the mega. After making the additions it ran all night.

Thanks for your time!
