I think everyone needs to take a deep breath and recognize a few things. 1) This is new product, and to expect military precision for its release does not seem reasonable, especially with a smaller

Please don't confuse a labor of love by a fellow HAM with a large company's professional product. I am appreciative of the development of this very innovative,state of the art, product by such a

This is one reason why I wait until a product it out and vetted before ordering one. Mike N2MS

I’m somewhat incredulous that people would urge a complete redesign of a product that is potentially days away from shipping, likely already built. The only issue is how to manage upgrades,

I sit corrected. But I wonder what the wireless in the Pico will be used for? Have to wait and see! [email protected]> wrote:

Guys, let's not speculate, the designer is not a fool. You already know him from his earlier offerings. I suggest, let's wait for the rollout and then discuss. Right now we don't know much of what's

Farhan explicitly stated the zBitx will have an RPi Pico W: " Hence, the zbitx sports a new microcontroller, the Raspberry Pico W (with Wifi and Bluetooth on it!) that handles the front panel. This

The Raspberry Pi Pico is $4. The Pico 2 (a newer version with more CPU power and flash memory) is $5. The wireless variants are an extra $2 but I don't think the zBitx is using one; it already has

The zBitx is called the zBitx because it is based on the RPi Zero 2 W (Zero Bitx), and the RPi Pico W is being added to compliment the RPi Zero 2 W, not replace it. As for the Pico vs ESP or other

Hi Rob, I wonder if there is a 2KOhm or so resistor that is not on the schematic?? That would explain the voltage on RD21.? With LD6 removed, the mic is out of the picture. Can you send a picture

The Pico brings something to the table that those alternatives do not: PIO peripherals. Those let you take most hardware protocols, including non-standard ones, and turn them into something that is

In general, GPIO is not the best way to interface a display IMO: it might lead you away from being able to use the GPU, and even worse, maybe you’ll waste cycles with bit-banging. (It’s been that

Alternatively, I would ask , why a PICO and not an ESP32 ? Cheaper also ! Regards VU2UPX [email protected]> wrote:

Rob, is this with mic or mic unplugged/disconnected ?

Thanks everyone for the discussion, much appreciated. I did find a typo in my measurements documentation. The base is 2.9 v not 3.9. That resolves the concern with QD1. Using a fluke 8062 to measure.

Farhan might I ask whi the pico and not just add a pc8575 or pc8574 i2c gpio expander into the mix if you need more gpio. I think the z2w over pico w is alot better and mre power performance.

sbitx is being praised while zbitx is being talked about. Those who have little knowledge of the knowledge of certain components believe that one day it will be able to do what the sbitx can do with

QD1 is toast, the base to emitter voltage is too high! Recheck and if you find Voltage between base-emitter is much more that say 0.7 volts then replace the transistor and you audio will be

Aaron, The radio works out of the box, have no doubts. However, you can tinker with it if you want to, but no one insists on it. The sbitx wouldnt be what it is without the contributions of so many
