be interesting to see how they get on....penetrating this market is not going to be quite as easy as it was with the pi.......they are going head to head with espressif....

espressif was adopted early on by the arduino community and so benefits from the ide and all the libraries, not to mention that the esp32 has twice as much memory and is twice as fast and has more ports exposed....but the pico is cheaper(marginally)..

these are interesting times we live in.....I don't think I'll be placing any bets on the outcome of this one.

Not sure that they're that worried.

It's a different ecosystem, and simple is good for a lot of stuff.

Printed out a test 'case' for the PI running as my music streamer

Repositioned the PI to the edge of the base so the phono and power sockets face backwards.
Network and USB ports on the left.
Bought a cable to go from the PI to the screen but turns out the screen is not using the standard format so 'tweaked' the cable I bought and now all is good as can be seen below:

Will design a new case which will allow me to easily add sides and back.

Nice - be interested how it all turns out...

Re the Pi Pico... There is a whole ecosystem around it and masses of documentation.

See https://www.raspberrypi.org/blog/raspbe ... w-on-sale/

One interesting point is their approach to upower - there is no WiFi etc and the chip is designed for low power use, unlike the ESP32.

I don't think that they're competitors - they're two very different beasts.

You've peaked my interest Nick and I can't shake the feeling that you're defending it unnecessarily...so I did a bit of digging and found this:

I disagree, I see them as competitors and apart from a different processor they seem to be the same beast(wifi excepted), inasmuch as they do exactly the same thing.

WiFi and Bluetooth excepted...

I wasn't intending to be defensive - I just think that they are for different parts of the IoT space.

You wouldn't really run an ESP32 on a battery (maybe a car battery...) but could genuinely consider that for a Pico, and that's a significant USP.

that was my point really....the datasheet shows less current usage for esp than that referenced in the pico doc I linked to(although to be fair that wasn't the datasheet published by the manufacturer). The main takeup for the esp32 with the sim800 modem is for battery use. There is even a charger circuit on the board for a lipo. If the modem version is aimed at battery use then the version without a gsm modem is surely going to go the distance......now you've got me defending the bloody esp, which wasn't ever my intention.

Notwithstanding, battery use is going to be entirely down to what you're hanging off the board in the way of peripherals

I took the plunge and got a pi touchscreen from pihut and plugged it in this afternoon. Installed jivelite on the pi and that's it, easy as that. Just starts working, remarkable. All credit to the picoreplayer chaps and ralphy, top stuff.

I've got the Allo Boss Dac attached to the pi, and if it allowed direct connection to a hat amp I'd have got one of those too to use in a standalone solution in the kitchen. I'll get a cheap 3116 amp instead and a separate PS.

But now I think I want one in my play room/office too cos the screen is really nice! :-) £60. What's not to like.

Changed the DAC HAT on mine to an R2R one.
Very nice sound coming out now and better for cabling - see pics:

From audiophilediyer.com - the discrete R-2R DAC HAT - hand made and pretty good.

Picked up a tip on PinkFish to repurpose an unused touch as the screen for picoreplayer by syncing the two together. Works perfectly!

Neat demonstration of augmented reality with a Pi Pico as an example...

'twould seem a number of the usual suspects have taken on board the importance of the RP2040 that is the heart of the pi pico.
there are offerings from sparkfun, but maybe more importantly, Arduino have taken it on by extending their nano range. I mention this because it opens up the use of the Arduino IDE which I suspect will make it(Rp2040) v. popular.

https://blog.arduino.cc/2021/01/20/welc ... ntrollers/

I don't know too much about it, but I can't help thinking that Atmel sold at the right time....this field is getting very crowded.

It's a really nice little board - I want to see what the current consumption is like, i.e. is real, unattended and off-grid, IoT usage possible. If it can compete with MSP430-series on that level, it'd be great. I haven't used an ATmega for years now...

Personally, I absolutely hate the Arduino IDE as from a professional standpoint it's very limited - you can get Arduino support for Eclipse, which is wonderful as it's a common environment for lots of devices & ICEs etc. that I use and has Git and a bazillion other plugins that just "work".
