ISM4334x-L77-EVB User’s Guide ISM43341-L77 EVB Wi-Fi, Bluetooth and NFC Radio Only Evaluation Board User’s Manual DOC-DS-20095 www.Inventeksys.com Page 1 Inventek Systems ISM4334x-L77-EVB User’s Guide 1 General Description The Inventek ISM43341-L77 is a single-chip quad-radio device that provides the highest level of integration for a wireless system, with integrated dual band (2.4 GHz/ 5 GHz) IEEE 802.11 a/b/g/n /baseband/radio. In addition to Wi-Fi, the chip also provides Bluetooth 4.0, and a low power NFC controller. The ISM43341-L77-EVB is a radio only solution that is ideal for integration with a single board computer running Linux. The evaluation board plugs directly into an SDIO/MicroSD slot and can be used with an ARM or x86 host processor running Linux Kernel 3.10 or later. Inventek Systems provides Wi-Fi and Bluetooth drivers for several different platforms. Hardware Features:         Uses Broadcom BCM43341/0 802.11 a/b/g/n Wi-Fi Radio Bluetooth 4.0 including BLE support. Near Field Communication (NFC option) 2.4 & 5 GHz chip antenna for Wi-Fi and Bluetooth . o U.FL Connector for external antenna Host interfaces: o SDIO: WiFi o UART: Bluetooth o I2C/UART/SPI: NFC Input Power: 3.3 V Dual port FTDI for NFC and Bluetooth HCI over USB FCC and CE approval 2 Part Number Detail Description ISM43341-L77-EVB Wi-Fi, Bluetooth, and NFC On board Antenna ISM43341-L77-EVB Wi-Fi, Bluetooth, NFC On board Antenna 3 Additional Documentation   ISM43340/1-L77 Functional Specification ISM4334x-L77_EVB_iMX6_Quick_Start_Guide_R3_AN20093 DOC-DS-20095 www.Inventeksys.com Page 2 Inventek Systems ISM4334x-L77-EVB User’s Guide 4 ISM4334x-L77-EVB Architecture 4.1 Powering the Board Two power connections are necessary to power the module:   VBAT VIO VBAT must be 3.3V, while VIO can range from 1.8 V to 3.3V. When using the ISM43341-L77-EVB, Inventek recommends connecting VIO and VBAT. DOC-DS-20095 www.Inventeksys.com Page 3 Inventek Systems ISM4334x-L77-EVB User’s Guide 4.1.1 Power Though SDIO   Place a jumper on J25, to connect VBAT and VIO. Place a jumper between pins 2 and 3 on J20, to tie VBAT to SDIO voltage supply. 4.1.2 External Power   Place a jumper on J25, to connect VBAT and VIO. Connect and external 3.3V Supply. Pin 2 on J20, is power. Pin 2 on J18 is GND. 5 Schematic 5.1 Radio, Power, & RF DOC-DS-20095 www.Inventeksys.com Page 4 Inventek Systems ISM4334x-L77-EVB User’s Guide 5.2 Host Interface Headers, Regulator and Config Switches 5.3 FTDI & NFC EEPROM DOC-DS-20095 www.Inventeksys.com Page 5 Inventek Systems ISM4334x-L77-EVB User’s Guide 6 Revision Control Document : ISM4334xC-Shield External Release Date 2/24/2016 Author KMT Wi-Fi module DOC-DS-20095 Revision 1.0 Comment Preliminary Release 7 CONTACT INFORMATION Inventek Systems 2 Republic Road Billerica MA, 01862 Tel: 978-667-1962 Sales@inventeksys.com www.inventeksys.com Inventek Systems reserves the right to make changes without further notice to any products or data herein to improve reliability, function, or design.
