Good afternoon,

Raduino32 v6 PCB is ready.?The board replaces the original Raduino, it is valid for uBitx v6 (also for v5 with some minor modifications). The original Raduino TFT display can be used.

It includes:

• 5v regulator LM7805.
• Dual polarity protection circuit (with relay or MOSFET). Optional use, the board can be powered from the uBitx.
• Sensor circuit for S-meter with LM386.
• Current sensing circuit with ACS712.
• Circuit to add Si5351 IC and Si5351 module socket (to choose).
• Socket to insert the ESP32.
• 2 x sockets to insert USB-Serial converter (Serial1 and Serial2).
• Socket to connect up to 3 DS18B20 probes (PA transistors and LM7805)
• 2 x sockets for A / D converter module with ADS1115.
• Socket to extend the uBitx audio connector.
• Socket to connect the future Raduino32-Audio board.
• Socket for connecting a 16 x PWM module with PCA9685.
• Socket for connecting a 16 x I / O module with MCP23017.

The board looks like this:


All SMD components are factory welded, except IC Si5351. You just need to add the LM7805 IC with its heat sink and the male or female pin strips.. The rest of the components are only necessary if you want to use the S-meter sensor, polarity protection, etc.

Due to the change of tax regulation in the EU, prices have increased, so you have to be careful when ordering.

If you order 5 units, each one costs € 12.50. If 10 units are ordered each one costs € 8. ((plus shipping costs from Spain to each interested person).

I would be grateful if anyone interested could send me a private message to know how many boards I should order. You do not need to pay anything up front, but you do need the "amateur commitment" to do so when the order arrives.?Possibly put them up for sale on eBay or Tindie to make the process easier.

I'll let a few days go by, for example until Monday, July 12, and then I'll place the order.



Thanks for your interest,
