WA2000

Introduction

The WA2000 is an upgrade to Tibbo's GA1000 Wi-Fi add-on module. Notable improvements include:

•Support for the 5GHz Wi-Fi band (802.11a and 801.11n standards).

•Support for BLE4.2 communications.

•WPA key calculation completely on the module, complex calculations in Tibbo BASIC/C are no longer necessary.

•Firmware stored in the module's flash memory, thus eliminating the need to send the firmware file into the module on every boot.

•The firmware can be upgraded from a Tibbo BASIC/C app or over-the-air (OTA), from Tibbo Updater iOS and Android apps.

•Wide operating temperature range: -40 ~ +85C.

The WA2000 is fully supported on Tibbo's ARM-based programmable devices: EM2000, EM2001, TPP2(G2), TPP3(G2).

The WA2000 is also partially supported on T1000-based programmable Tibbo products. Such devices can only access the Wi-Fi interface of the WA2000, as the BLE interface is not supported by related platforms. The devices are: DS1101, DS1102, EM1000, EM1001, EM1206, TPP2, TPP3.

Like the GA1000, the WA2000 utilizes an SPI interface and only requires five GPIOs to control. The module is supplied in two versions: the WA2000U with an U.FL connector for attaching an external antenna, and WA2000C device with a chip antenna onboard.

Please note that the WA2000 is a slave device and cannot be used on its own. This add-on will only work with one of Tibbo devices listed above.

Hardware features

•Supports the following wireless communications standards:

o2.4/5.0GHz Wi-Fi (802.11abgn);

oBluetooth Low-Energy (BLE4.2) (1).

•Nearly 100% backward-compatible with the original GA1000 device.

•Performs WPA key calculation completely internally.

•Requires only five GPIO lines to control.

•Internal firmware of the WA2000:

oStored in the WA2000's onboard flash memory.

oUpgradeable from a Tibbo BASIC/C app or over-the-air (OTA) (2);

oOTA updates may cover TiOS+Tibbo BASIC/C app of the host (2);

oTibbo supplies iOS/Android apps for performing OTA updates.

•L.U.I.S. app for iOS and Android facilitates convenient HTML5-based configuration of host devices through the BLE interface (3).

•Two antenna configurations:

oWA2000U -- has a U.FL connector for an external antenna;

oWA2000C -- carries a chip antenna onboard.

•Red status LED for connection indication (4).

•Power: 200mA @ 3.3V (active state with data transmission).

•Dimensions (LxWxH): 42.0 x 20.0 x 5.8mm.

•Prototyping-friendly 2.54mm (100mil) pin pitch.

•Operating temperature range: -40 ~ +85C.

•FCC-certified, FCC ID: XOJ-WA2000.

•CE certification pending.

(1) BLE is only supported on ARM-based Tibbo devices.

(2) Over-the-air (OTA) updates rely on the BLE interface and are only possible on ARM-based Tibbo devices.

(3) Requires a programmable Tibbo device running a Tibbo BASIC/C app supporting L.U.I.S. (through the use of the L.U.I.S. library).

(4) *"Connection" means a BLE link or a Wi-Fi association with an access point.*
