KC-21 This device is a light weight, low power option that comes from KC Wirefree, a small company out of Arizona who leads the industry of OEM Bluetooth Modules. most impressive about their device is the custom firmware they have What’s developed for it, kcSerial. This firmware is designed to be easy to configure and operate by providing an easy to use, character based AT command language. Configurations can be saved to the onboard flash memory, providing an easy way to customize your chips default startup settings and features. Since the other modules are flashed with the profile that the group requires, it is unlikely that this module would be picked for their firmware If needed, the other modules mentioned above are also programmable. Table 3.3.F shows comparison data below: Table 3.3.F - KC-21 Basic Spec List Property Value Bluetooth Versions 2.1 + EDR Data rate With onboard stack 300Kbps; HCI mode: 1.5Mbps sustained, 3Mbps burst Profiles SPP, DUN, HID, L2CAP, SDP Supply voltage 1.8V ± 10% Power consumption Low power connection modes < 500 µA; Peak current 90mA Operating temperature range -40C to +85C Integrated Chip antenna Antenna Size 15.2mm x 26.9 mm x 2.5 mm Weight 0.047 oz. Price $36.00 Bluetooth Module Decision After looking at even more modules than discussed above, it is clear that the technology is more or less equivalent and many modules meet the needs of the
