This is my atmega8 (and ATmega328 compatible) development board.
As it has the uart connector, you can program it in the arduino ide, if you are into that. You just need to download the bootloader through isp programming.
(I personally prefer to do it the expert way)
I added some connectors according to what I usually use:
I2C (also pull ups)
SPI (with an extra pin for devices such as nrf24,...
My version of arduino with ARK connectors and better voltage regulators.
Fully working board
This version of board allow you to upload your code via usb uning CH330N microchip
Now there is also 3.3V high current voltage regulator as well as 5V
