Note 1: DSR, DTR, RI, and DCD can be implemented in the smart BASIC application.
Note 2: With I2C interface selected, pull-up resistors on I2C SDA and I2C SCL MUST be connected
externally as per I2C standard.
Note 3: SPI interface (master) consists of SPI MOSI, SPI MISO and SPI CLK. SPI CS is created by
customer using any spare SIO pin within their smartBASIC application script allowing multi-
dropping.
Note 4: RM1xx module comes loaded with smart BASIC runtime engine FW, but does not come
loaded with any smart BASIC application script (as that is dependent on customer end
application or use). 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).
Standby Doze current TBD (typical).
Note 7: PWM output signal has a frequency and duty cycle property. PWM output is generated
using 32-bit hardware timers. The timers are clocked by a 1MHz (1uS period) clock source.
Trade-off PWM output frequency with resolution. For example:
PWM output frequency of 500kHz (2uS) results in resolution of 1:2
PWM output frequency of 100kHz (10uS) results in resolution of 1:10
PWM output frequency of 10kHz (100uS) results in resolution of 1:100
PWM output frequency of 1kHz(1000uS) results in resolution of 1:1000
Refer to the smartBASIC user guide for details.
