Bluetooth® SMART Module [Koshian™] is an outstanding development kit for "Makers" which can be used for the prototyping of such as IoT or wearable equipment without hardware design and the soldering. Koshian is a Bluetooth SMART module which is equipped with a WICED SMART™ SIP BCM20737S (TELEC certified) and implements the Konashi compatible firmware. Koshian can be plugged in the Konashi base board, Konashi mini extension board and also mounted onto the breadboard or the universal board through the end face through holes. "Makers" can easily transfer their development process from the rapid prototyping to the mass production phase with this Koshian module for the Konashi based IoT products.
