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