My man is in Shenzhen visiting his fam

They seem like the perfect radio  No library needed 

Digikey/fleabay are selling them for $80+ which is like > 400% markup   

Are they cool or what!

[raggedyanne]

I would really love to see the Monteino with this radio nudge nudge win wink 
I wonder how much $$ of an incentive Felix can be bribed with 

[raggedyanne]

What it is worth, i feel i got

Real New Old v0.2


Real and Old v1.2


My swelled ego got the better of me, for the record the ones on fleabay for $80+ are fake too 

It should have been obvious that their is no hope logo on theses, the soic package is scrubbed off & the not so obvious the crystal is in the wrong place lol.

I feel really ashamed, the item i bought is Version 0.2 , the other item is Version 0.1 , I feel dumb for listening to a seller who told me it was fake when it wasn't.

My apologies.

The more i look the more i want to

Hi Raggedy,

Are this similar the the RFM95 with a UART?
What is the advantage?

Interesting, so a RF95. You'd be limited by the MCU firmware and whatever modes that implements, sorry I haven't studied the DS to really tell.
Also I see some LED's on there, unless the firmware can turn those off, the low-power-folk would probably not accept the LEDs.

[raggedyanne]

I have to modify it again (& again)  , since i have better information now.
If you're a true miser , you would remove them.

It's a complete RF95 with a UART.

It's a complete RF95 with a UART.

I tend to like the SPI modules better because of the inherent unreliability of UART's. If you have a MCU with SPI support why settle for UART?

[raggedyanne]

Each to their own 

• Your not relying on somebody else
• There is less overhead
• Easier to debug
• Easier to manage

+1 for the unreliability. This really counts when your timing is sensitive.
I personally hate AT UART interfaces.

Ok
