RC-WLE5-868 RC-CC1101-SPI-434 RC-WLE5-868-HA Lora Wireless Module STM32WLE5 based RC-WLE5-868 is an ultra low power long range device designed by RadioControlli. The module is based on STM32WLE5J8 device from STMicroelectronics. The STM32WLE5 long-range wireless and ultra-low-power devices embed a powerful and ultra-low-power LPWAN-compliant radio solution, enabling the following modulations: LoRa®, (G)FSK, (G)MSK, and BPSK. These devices are designed to be extremely low-power and are based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 48 MHz. This core implements a full set of DSP instructions and an independent memory protection unit (MPU) that enhances the application security. The devices embed high-speed memories (flash memory 64 Kbytes, SRAM up to 64 Kbytes), and an extensive range of enhanced I/Os and peripherals. The main applications of this module are Internet of Things devices and wireless sensor networks , especially battery powered low power consumption long range. Operative Frequency bands : 868MHz/915MHz. Ready for use SMD mounting (13 x 14.5mm) - Metal shield. For more information and details, please refer to the STM32WLE5J datasheet (www.st.com). Module Information : Standard Version (UFL Connector) Helical Antenna Version RC-WLE5-868 is designed to be easily integrated into your hardware application, we provide 2 versions: 1) Standard version with UFL connector You can use the UFL connector where you can directly connect the antenna. 2) Version with helical antenna (full version) Applications: ● ● ● ● ● ● Smart meters Wireless security systems Home and Building automation 6LoWPAN systems Automatic Measure Reading Low-Power Wireless Systems Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to change in whole or in part these information without notice.

RC-WLE5-868 RC-CC1101-SPI-434 RC-WLE5-868-HA REFERENCE SCHEMATICS Software Upgrade through USART Normally BOOT0 (PH3) must be connected to GND When is necessary to make an USART firmware upgrade, the BOOT0 (PH3) must be connected to VCC. Software Program through ST-LINK While programming through ST-LINK it’s not necessary to connect BOOT0 to VCC. RF Switch Control The RF Switch that select the TX/RX of the module is controlled by the STM32WL5 using two GPIO (PC3 and Pc4). These GPIO aren’t output in the module footprint, must be driven through the firmware (see table below). PUSH BUTTON USART FIRMWARE...

RC-WLE5-868 RC-CC1101-SPI-434 RC-WLE5-868-HA RECOMMENDED HARDWARE DESIGN: 1) Hardware All unused pins should be left floating; do not ground. All GND pins must be well grounded. Traces should not be routed underneath the module. 2) Power Supply The transceiver module must be powered from a regulated voltage. It is recommended to keep the power supply line for VCC as short and low impedence as possible. Near the power pins it is recommended to insert a ceramic the decoupling capacitor (100nF). 3) Ground Plane It is recommended to have a copper ground plane under the shielded zone of the module....

4) Module Placement The antenna on the PCB has an omnidirectional radiation pattern. To maximize antenna efficiency, an adequate grounding plane must be provided under the module. Instead the areas underneath and surrounding the antenna area must be free of copper. adio lontroMi Not Recommended location XY plane RECOMMENDED REFLOW PROFILE (LEAD FREE SOLDER) Peak temp C 232~255 C 222 C 180 C 150C Ramp up rate (to reflow) Soldering Zone Radiocontrolli s.r.l refuses any responsibility for irregular uses of the devices and for any possible lack or inaccuracy of the data and reserves the right to...
