the pitch is smaller than 2.54 but can be soldering.has no baseboard that logic level converter (3.3v5v).13, the lowest price of JDY-08 was about $2.1 and after a month it dropped to $1.73 and now $1.64. So, the main pros of JDY-08 are the price. (Some alternatives of CC2541 are Nordic nRf51822, Dialog DA14580)Īnother BLE module, HM-11 has small form factor. But, be careful about the difference of firmware. These module using same Bluetooth LE chipset that is Ti CC2541.Īnd circuit is very similar. These modules can be found at Aliexpress or any Chinese market. And there are many clone models like AT-09. In BLE (Bluetooth Low Energy) domain, HM-10 is popular. I think HC-05 and HC-06 are the most popular Bluetooth module.
If you ever heard about JDY-08, let me a summary about Bluetooth modules for Arduino. datasheet -> JDY-08 Bluetooth LE Module Datasheet - Google Docs.I made Fritzing part and translate datasheet using google translation and refine format. I'd like to share some stuff about JDY-08 BLE module.
