I am looking for the schematic for the Bluetooth Smart Communication Interface Board (SB_CIB_vB).
You are able to check the SB_CIB_vB schematics from Bluetooth® Smart Communication Interface Board (UM-B-065) user manual. For downloading it, please visit our portal page https://support.dialog-semiconductor.com/ and then enter to the “Connectivity: Bluetooth low energy & 802.15.4”. From the top menu bar click to the “Ref Designs” and then select the “Wearables -> IoT Sensor Development Kit”. Please, scroll down and you will find the UM-B-065 document.
