About this item
- 0.91 inch OLED display --- This is a 40 pin expansion board type Raspberry Pi HAT that provides a 0.91 inch screen connected to the I2C pin. The display information can be adjusted via the program.
- Speed adjustable fan --- It provides an ultra-thin 4007 fan to support heat dissipation.
- Programmable LED display: on the back of the board there are 4 adjustable LED lights. You can also control the lighting mode of the LED lights by simple programming.
- Expandable GPIO interface: the previous hat board design is used. Users can still access the 40Pin GPIO without any problems. The new mounting method avoids the risk of short circuits caused by metal parts and ensures an attractive design.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
