2. Introduction of RTBTM01 BLE Module Board
RTBTM01 is a Bluetooth low energy module based on Renesas MCU R5F11AG Bluetooth Low Energy
consumption RF transceiver supporting the Bluetooth ver.4.1 (Low Energy Single mode) specifications.
This module has integrated RF Antenna, 32MHz Crystal, DC/DC inductor to make it easy to use in the
application product without requesting know-how of sensitive circuitry and RF design technics. Customer can
optionally use RF connector, RF pin or RF chip Antenna on module for end-product development.
RTBTM01 is capable to operate either modem (as default) or embedded mode for the sake of cost saving and
product size reduction. Embedded firmware is optionally available and in this case, customer may contact
RFCOM Technologies for further information.
RTBTM01 BLE module is ROHS, CE, FCC Part 15 and RCM pre-approved module. Customers can directly
adopt this module so as to delivery their products to market more efficiently.
