Inventek Systems ISM43341-L77-EVB Wi-Fi Bluetooth and NFC Radio Only

Evaluation Board

Product Information

The ISM43341-L77-EVB is a single-chip quad-radio device that provides the highest level of integration for a wireless system. It features integrated dual band (2.4 GHz/5 GHz) IEEE 802.11 a/b/g/n baseband/radio, Bluetooth 4.0, and a low power NFC controller. The radio only solution is ideal for integration with a single board computer running Linux. It uses Broadcom BCM43341/0 802.11 a/b/g/n Wi-Fi Radio, Bluetooth 4.0 with BLE support, and has an optional NFC feature. The board has a U.FL Connector for an external antenna and supports host interfaces such as SDIO for Wi-Fi, UART for Bluetooth, and I2C/UART/SPI for NFC communication. It operates on 3.3V input power and has FCC and CE approval.

Product Usage Instructions

1. Powering the Board:
   • Two power connections are necessary: VBAT and VIO.
   • VBAT must be connected to a 3.3V power source.
   • VIO can range from 1.8V to 3.3V.
   • When using the ISM43341-L77-EVB, it is recommended to connect both VIO and VBAT.
2. Power Through 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 the SDIO voltage supply.
3. External Power:
   • Place a jumper on J25 to connect VBAT and VIO.
   • Connect an external 3.3V supply to pin 2 on J20.
   • Pin 2 on J18 is GND.

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.

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.

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.
