AS UNO-20 (AS-UNO-16)
This is my own design - UNOs and Nano are getting scarce... and pricey...

I laid it out as per my own preference - Bus oriented - one 8 bit, and two 6 bit parallel buses.

It has a socketed ATmega328P, although the socket doesn't show in the 3D rendering.
You can choose a 16 or 20 MHz crystal.

There is no USB to UART on-board - designed to use a CP2102 board.. although there is no reason you could not use an FTDI, for example.
But you would have to use jumpers to connect it to the CP2102 header.

LEDs are installed optionally - in case you are running on battery.

Separate I2C header designed to use an 0.91" OLED display.  An example sketch is available on my GitHub.

There are 100s of possible header pin combinations - see the related products tab to grab the ones you want when ordering a BareBones.

I'm happy to announce that rev. 0.9 came out proto-perfect (electrically, at least)  You can program it just like an Arduino UNO.  I recommend you use the miniCore board package if using 20MHz.

The mechanical layout error prevents the use of downward facing pins on the A0-A6 header for bread board installation.  Will be fixed in rev. 1.0

The Kit includes MPU with bootloader, socket, crystal, 2 LEDs and headers.
Feel free to ask for the configuration of your choice. ( LED colour, male/female headers etc.)

ESP32-S2 proMINI
ESP32-S2 BreadkOut Junk (ESP32-S2 proMini junk)
Our own design - we call it an ESP32-S2 proMINI
some layout errors and 1 omission on this one...
need to use jumpers for serial upload.
see my github for more details..

ESP-01 (ESP-01)
this is actually an older version of an ESP-01S

it has the slower flash - you need to set the flash speed to 20MHz
in the IDE tools.

other than that it works fine..

ATtiny85 Nano dev kit with LEDs
ATtiny85 Nano - Junk (ATtiny85nanoJunk)
Now in Stock: - This one has a boo-boo on the silk screen - The LEDs have a "TN" prefix - the rev number is erroneously shown as 0.9.  Electrically it has no problems....

ATtiny85 Dev Kit with SPI ICSP connector,
Reset Button and 5 LEDs

Designed for use with a CP2102 USB to Serial board if you want Serial.
Designed to be programmed with a USBasp.

May be used with ATtiny85 or ATtiny13A

suitable for BreadBoarding - pins included but not soldered.

The BareBones option is PCB Only - missing:
       DIP-08 Socket.
       male header pins for ICSP and Breadboard pins.
       6 pin female Header for CP2102.

see the related products tab for options to the BareBones model.
