DWM SOM implements well established versioning and tracking mechanisms:
 
−
 
 
−
* PCB version is copper printed on PCB itself, as shown in Fig. 1
 
−
* serial number: it is printed on a white label, as shown in Fig. 2: see also [[Product_serial_number | Product serial number]] page for more details
 
−
* ConfigID: it is used by software running on the board for the identification of the product model/hardware configuration. For more details, please refer to [[ConfigID_and_UniqueID | this link]]
 
−
** (''TBD: definire/identificare dove è memorizzato il CONFIGID nel prodotto in questione'') On DWM SOM ConfigID is stored in these areas of OTP

Introduction[edit | edit source]

The module is built around an LS Research TiWi-BLE Integrated Transceiver Modules for WLAN 802.11 b/g/n and Bluetooth. The module implements the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over a SDIO interface. The module also provides a Bluetooth platform through the HCI transport layer. Both WLAN and Bluetooth share the same antenna port.

Features[edit | edit source]

  • Based on Texas Instruments WL1271L Transceiver
  • IEEE 802.11 b,g,n,d,e,i, compliant
  • Bluetooth 2.1+EDR, Power Class 1.5
  • Full support for BT4.0 BLE and ANT
  • Reduced footprint: 25 mm x 38 mm
  • Low height profile
  • U.FL connector for external antenna
  • Integrated band-pass filter
  • Industrial operating temperature range: -40 / +85 °C

Interface timings[edit | edit source]

Please refer to the TiWi-BLE Datasheet for SDIO [WiFi] and UART [Bluetooth] interface timings.
