VERVIEW AND EATURES This Hardware Integration Guide describes both the RM186 (868MHz band for EU) and RM191 (915MHz band for US). The differences will be outlined in the Radio Specifications. Every RM1xx Series module is designed to enable OEMs to add a long range LoRa radio link as well as central role Bluetooth Low Energy (BLE) to small, portable, power-conscious devices.

Laird provides many sample smart BASIC application scripts covering the services listed. Additional applications being added every quarter. Note 5: Laird suggests using Vcc of 3.3V +/-5% (3.13V-3.46V) for maximum LoRa output power. WARNING: above 3.5V, the LoRa transmitter will be disabled to maintain regulatory compliance Note 6: Deep Sleep current <1000nA (typical).
865 – 870MHz (250 – 11000 bps over the air data rate) RM186 protocol can optionally employs 50kbps FSK when enabled by the gateway RM191 Lora radio: 902 – 928MHz (980 – 21900 bps over the air data rate) ...
RS-232 level compliant interface. Some serial implementations link CTS and RTS to remove the need for handshaking. Laird does not recommend linking CTS and RTS other than for testing and prototyping. If these pins are linked and the host sends data at the point that the RM1xx deasserts its RTS signal, then there is significant risk that internal receive buffers will overflow, which could lead to an internal processor crash.
FET transistor in conjunction with a low resistance voltage divider. High impedance values of a voltage divider connected to an AIN pin will introduce ADC inaccuracy. Laird recommends the following solution for setup of a voltage divider when used with the RM1xx ADC: –...
OUNT ODULES Introduction Laird Technologies surface mount modules are designed to conform to all major manufacturing guidelines. This application note is intended to provide additional guidance beyond the information that is presented in the User Americas: +1-800-492-2320 Embedded Wireless Solutions Support Center: Europe: +44-1628-858-940 http://ews-support.lairdtech.com...

13 days 9 days Laird surface mount modules are designed to be easily manufactured, including reflow soldering to a PCB. Ultimately it is the responsibility of the customer to choose the appropriate solder paste and to ensure oven temperatures during reflow meet the requirements of the solder paste. Laird surface mount modules conform to J-STD-020D1 standards for reflow temperatures.
SQG-RM191 3147A-RM191 The OEM must follow the regulatory guidelines and warnings listed below to inherit Laird’ modular approval. The RM191-SM holds full modular approvals and has been certified for integration to products only by OEM integrators under the following conditions: 1.
Page 31
WARNING: The OEM must ensure that FCC and Industry Canada labelling requirements are met. This includes a clearly visible label on the outside of the OEM enclosure specifying the appropriate Laird FCC identifier for this product. Contains FCC ID: SQG-RM191...

The OEM should have their device which incorporates the RM191-SM tested by a qualified test house to verify compliance with FCC Part 15 Subpart B limits for unintentional radiators. WARNING: Changes or modifications not expressly approved by Laird could void the user’s authority to operate the equipment. FCC Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
CE R EGULATORY The RM186 has been tested for compliance with relevant standards for the EU market. The RM186 module has been tested with a 2.0dBi external dipole antenna for LoRa, and the -1.5dBi on-board chip antenna for the BLE transmitter.

-1.5 RM191-SM Note: The RM186 module internal BLE chipset IC pins are rated 4 kV (ESD HBM). ESD can find its way through the external 2-Wire SWD Programming/Debug Interface connector (if used on the customers design), if discharge is applied directly. Customer should ensure adequate protection against ESD on their end product design (using the RM186 module) to meet relevant ESD standard (for CE, this is EN301-489).
Declaration: We, Laird, declare under our sole responsibility that the essential radio test suites have been carried out and that the above product to which this declaration relates is in conformity with all the applicable essential requirements of Article 3 of the EU Directive 1999/5/EC, when used for its intended purpose.
