Looks like with the "Plus" version you can only know if it is charging or not..
I'm waiting for a reply on this topic to know more about the options left:

Did you try the bootloader mode to upload a new sketch? It is described in the "Notes" of the TinyScreenPlus shop page:

If you were able to upload a sketch to the TinyScreen+ and now it does not respond, you may need to force this into bootloader mode. To do this, power off the TinyScreen+ using the slide switch. Plug the USB cable into the TinyScreen+ and your computer. Then press and hold the button closest to the USB connector while sliding the switch to the ON position. Then try uploading your program to the TinyScreen+ and it should work. You may need to try this several times if it does not work the first time.

Ok found my own answer:
Yes.

The pins available on the proto boards are directly accessible on the expansion port.
It is very tricky and difficult to solder to, but possible.

My approach:
I've used the plug of another board, removed all pins but the one GPIO I wanted to use and the two GND pins, then soldered the buzzer to the pins and plugged it in. Works flawlessly

So.. any update on that by now? I could make good use of flatter versions of the stack compared to the current setup I have with the TinyScreen+.
The only mentioned new productions I could find are the Blog post from April:

I guess the image at the end of the post is supposed to be a teaser?

Will the new product line also include an update to the TinyScreen+ to support the new connector?

Hi,

I'm working on a project involving the TinyScreen+ and the EEPROM board.
I plan to remove the bottom expansion port of the EEPROM board to save some millimeters in space. and this way can access the pins easier, which brings me to my question:

Is it possible to hook something up to the IO8 pin (25 on the connector) directly?
I plan to attach a piezzo buzzer for 8 bit audio and want to save as much space as possible.

Hi, I'm waiting for two of the 433MHz transceivers to be delivered and started to look into this as well.
For now I could not find any Tinyduino-specific examples, but I've stumbled upon this library:
https://andreasrohner.at/posts/Electronics/New-Arduino-library-for-433-Mhz-AM-Radio-Modules/

It looks promising.
It's supposed to be an alternative to the existing VirtualWire and RadioHead libraries. VirtualWire seems to be not maintained right now and RadioHead is a bit complicated to use imho.

I'll post an update when I have received my own devices or if I find any other solutions.

Hi, I would also like to know how this could be done!

The only information I've found so far are rather complex "hacks" to estimate the data:

(look for the displayBattery() function)

Is there an achievable way of modifying the TinyScreen+ board to get a voltage readout of the battery and maybe even a charging state?

Can some of the TinyCircuits staff help here?
