STEVAL-FKI868V1

STEVAL-FKI868V1 Sub-1 GHz transceiver development kit based on S2-LP Data brief   USB interface RoHS compliant Description The STEVAL-FKI868V1 evaluation board is based on the S2-LP sub-1 GHz ultra-low power low data-rate transceiver, suitable for ISM bands and Wireless M-Bus. The main board is the NUCLEO-L152RE development board, equipped with a low power microcontroller STM32L to control the S2-LP and the ST-LINK/V2-1 debugger and programmer for firmware updating. Features             S2-LP narrow band ultra-low power sub-1 GHz transceiver in a standalone RF Module tuned for 860 - 940 MHz frequency bands STM32 Nucleo development board with STM32L152RE MCU Suitable for Wireless M-Bus systems Associated S2-LP development kit including, documentation, firmware for STM32L and GUI Programmable RF output power up to +16 dBm Modulation schemes: 2-FSK, 2-GFSK, 4FSK, 4-GFSK, OOK, and ASK Air data rate from 0.3 to 500 kbps Ultra-low power consumption:  6.7 mA RX  10 mA TX at +10 dBm Excellent performance of receiver sensitivity (up to -130 dBm) Low duty cycle RX / TX operation mode Automatic acknowledgement, retransmission, and timeout protocol engine SPI interface for microcontroller November 2016 DocID029972 Rev 1 For further information contact your local STMicroelectronics sales office 1/4 www.st.com DocID029972 Rev 1 CON 6 CN 4 CON 8 CN 3 CON 8 CN 2 CON1 0 CN 1 1 2 3 4 5 6 1 2 3 4 5 6 7 8 8 7 6 5 4 3 2 1 C1 C_4 .7U_060 3 10 9 8 7 6 5 4 3 2 1 0 R7 0 0 0 0 0 R1 4 R1 5 R1 6 3V 3 1 GP IO3 0 2 C3 VD D NM VSMPS 2 R2 0 XTA L Y1 L_TBD_040 2 C1 9 R2 1 0 ohm L1 C5 VD D VDDSMP S SMPS 1 SMPS 2 XOU T XIN SD N R1 8 NM C3 0 C_470 n_040 2 VSMPS 2 C_470p_040 2 C2 5 VDDANAS YNT H S2 -LP 1 2 3 4 5 6 U2 C_100p_040 2 C1 1 L6 L_TBD_040 2 C_12p_040 2 C2 0 SD N C6 C_100p_040 2 VDDANAS YNT H C_470 n_040 2 C1 0 VDDSMP S L_10U_080 5 L2 C_470 n_040 2 C1 2 C_1 u_060 3 C4 C_100p_040 2 VDDVCOT X C_12p_040 2 C3 2 C_150 n_040 2 C_470 n_040 2 Vsmps_e xt GP IO0 CS N VD D R1 3 0 R1 2 JP 1 2 Jumpe r2 SCL K NM CS N SCL K SD O C3 3 C_100p_040 2 NM R9 SD I SD N nS 0 GP IO1 GP IO2 1 R1 1 0 R1 0 R5 R4 R6 C_150 n_040 2 C2 VDDSMP S VD D R1 9 NM C3 1 C_100p_040 2 VRS YNT H C1 7 C_TBD_040 2 C2 6 C_150 n_040 2 C3 4 VSMPS 2 C2 7 L_TBD_040 2 L8 C1 8 C2 8 C1 6 C2 4 C_TBD_040 2 L_TBD_040 2 L1 0 C2 9 C_TBD_040 2 C_TBD_040 2 C_TBD_040 2 C2 1 J1 RF_ IN/OU T C9 C_100 n_040 2 R3 R_100k_040 2 3V 3 C_TBD_040 2 C_TBD_040 2 L_TBD_040 2 C_TBD_040 2 SCL K SD I L_TBD_040 2 L4 L_TBD_040 2 L3 L_TBD_040 2 L9 8 7 6 5 C_TBD_040 2 M9564 0 VD D L5 C3 5 C_100p_040 2 NM R2 2 C_TBD_040 2 C1 5 U1 R2 R_100k_040 2 nS Vc c Q nHOL D nW C Vs s D C1 3 1 2 3 4 C_TBD_040 2 nS SD O C_TBD_040 2 C1 4 R1 7 NM C2 3 C_100p_040 2 18 SCL K 17 SD I 16 SD O 15 VDDR XDIG 14 13 L_TBD_060 3 L7 C2 2 C_150 n_040 2 R1 R_100k_040 2 C8 C_100p_040 2 VDDR XDIG SCL K SD I SD O VDDR XDIG RXP RXN VSMPS 2 C_470 n_040 2 C7 GP IO3 GP IO2 GP IO1 GP IO0 CS N 24 23 22 21 20 19 VRD IG GP IO3 GP IO2 GP IO1 GP IO0 CS N VDDANASYNT H VRSYNT H VREFVC O VDDVCOT X TX VRR F 7 8 VRSYNT H 9 VDDVCOT X 10 11 12 2/4 GN D 1 25 VD D Schematic diagram STEVAL-FKI868V1 Schematic diagram Figure 1: STEVAL-FKI868V1 circuit schematic GSPG04 11161000SG STEVAL-FKI868V1 2 Revision history Revision history Table 1: Document revision history Date Version 10-Nov-2016 1 Changes Initial release.
