There's thousands of people on this forum with thousands of different opinions of when it's appropriate to start a new thread. I'm perfectly fine with having a conversation that goes somewhere. And if

Yes, the "RobotDyn SAMD21 M0-Mini" is very similar to the "Protoneer" but 2x to 3x more expensive and I don't see any advantage, offhand ??? ? 73 Kees K5BCQ

He asked if there were other small boards out there. I suggested one. The STM32 boards come in several flavors, including one that uses the Arduino NANO layout, called the Blue-Pill board. They are

Guess the Topic is LOW END NANO Replacements with more memory/function .....like the Protoneer boards, STM32F103C8T6 boards, and ?? Not worth starting ...another... thread. 73 Kees K5BCQ

Yes, the STM32F103C8T6 boards ("blue pill", "black pill") are another very low cost (<$3) alternative and it looks like the market is being flooded with them. It will require someone more experienced

I have a CW filter from New England QRP the NESCAF switched capacitor audio filter. Mine works great with the uBITX and others have had good success as well.? It lets you very both center frequency

What does that have to do with this topic? rOn

Thanks for setting up a new thread, Gary. I bet Protoneer wonders where all the orders are coming from.....the power of uBIT-X and a lot of builders. Apparently this has been out there for a number

I am just waiting to receive the micro bitx then I will start the experimentation. The idea is to use the bitx as a development board for the additional am/fm components. Meanwhile I started to create

Unfortunately, the ubitx.net website only lists the 1.072 manual version. Ron W7HD

Have you seen ubitx.net ?? A lot of hard work went into aggregating the information generated here.

The reason the Raduino regulator greats so hot is it has to dissipate the heat generated from in your case the 8.8 voltage drop across it. To cool it down you can insert a dropping resistor of about

Good marketing!
