As the microview.h is open source - I was wondering if someone would do this!

Was just browsing and found my design here. I'm a pcb designer and have created many small projects that use the larger 128x64 oled displays. On my last order I grabbed a few smaller ones that were not being used for anything. The microview type project came along and after seeing the code on github I created a simple board to use the display. No real purpose in mind and it's not useful in any way. None of the I/O are broken but it will run a few example sketches. This board has the Arduino Pro or Pro Mini 328P/16Mhz bootloader installed, a small temperature IC, FT230XS USB chip and a LiPo charger. The schematics and gerber files are all up for grabs if you want them.

Hi Mike, glad you've joined the forum! Hope you didn't mind me posting your video - was very interested by it.

How much would your MicroClones cost to make?, there is a bit of a shortage of the microviews presently!

I found this video of yours - is this a 128x64 one??

I've never done a total because I've already had all the parts that I need for my store products on Tindie: https://www.tindie.com/stores/miker/
Digikey sells most of them and the glass is at Buy-Display.com. Attached is the BOM that has most of the part numbers and a schematic. The Oled power net should be VCC so I needed a jumper wire to fix it.

I like your pong clock! https://www.tindie.com/products/miker/pongclock-complete-kit/
So that is like a MicroView with bigger screen and a button at the back? [biggrin]
What is the graphics library like which you used to program it?
One of the things I like about the microview.h is that since MLxxxp did some low level optimisations, screen updates are very fast. I've got no idea what other libraries are like.

The base unit which you connect this screen to, seems to have a couple of buttons. It looks ideal for my use, is that available from your shop? https://www.tindie.com/products/miker/096-oled-i2c-display/

The PongClock runs at 8Mhz and has an i2C display. It uses the Adafruit graphics driver. It's pretty fast but not nearly as fast as the MicroView SPI. That things crazy fast. The PongClock has two buttons for changing the time, brightness, Pong or Tetris mode... A customer wrote the code for that one. I'm strictly a hardware guy. 

All items on Tindie are up for grabs

Oh yes found the base unit now https://www.tindie.com/products/miker/arduino-sensor-board/

The Lipo rechargable battery seen on your boards, can that be recharged via the micro-usb? I would imagine that would need some charge circuit chip, or controlled by some code, to have that possible?

My 2nd post has a schematic attached showing the charger circuit. It can charge the battery fast with the power switched off or trickle charge the battery while the device is running.

I want them.
Please send me the schematics and gerber file.
And Will contact with me by e-mail.
