PCI Express

PCI Express (PCIe) slots are replacing PCI slots within desktop PCs and servers, they have a similar form factor and user experience as the older PCI cards, however they are both faster and require less power and are becoming the card type of choice. Brainboxes PCI Express cards will fit in any PCI Express slot - x1, x4, x8 & x16. We manufacture an extensive range of PCI Express cards with 1 to 8 ports, RS232 or RS422/485, that come with LPT option, and with or without cables.


Bluetooth is a simple instant radio solution that allows different devices to communicate without cable connections. Since Bluetooth devices are radios, they can even communicate through walls and upto distances of 100m.
Brainboxes BL-819 and BL-830 are bluetooth to serial adaptors, they require no driver software to be added to the PC or the peripherals and so are ideal instant cable replacements.


Brainboxes PCI cards are compatible with both 5V and 3.3V slots, they universal PCI cards, uPCI.
