Pin Alignment

CN2 (General-Purpose Connector)

EvalKit_J4

Almost all pins connectable to the wireless engine of the ZigBee/IEEE802.15.4 module are consolidated to CN2 on the sensor node of the ZigBee / IEEE802.15.4 Evaluation and Development Kit. Pin alignment is shown below.

The only difference from J4 of our former kit TWE-EK-001 is Pin 38 (GND for EK-001 and FWP (Flash Write Protect) for EK-002). Connect FWP to either GND or VCC. For details on this pin, see the WP pin of the SPI Flash (or M25P40 for TWE-001 and 001STRONG). If evaluations do not require strictness, this pin can be open.

J9 and J11 (UART)

The following shows the pin alignment of J9 and J11 on the sensor node of ZigBee / IEEE802.15.4 Evaluation and Development Kit that are connected to UART0 and UART1:

Pin No. Signal Type Description

EvalKit_UART_J9,11
EvalKit_UART_cable

The USB-UART connection cable is connected as shown in the figure on the right. Make sure to insert the cable in the correct direction.

JP4 and JP6 (Jumpers to Select Power Source)

You can select the power source for use by means of a jumper.

Set up the jumpers for JP4 and JP6 on the sensor node of the ZigBee / IEEE802.15.4 Evaluation and Development Kit, according to the procedure below:

AC adapter

Connect the jumper pins to JP4 (1-2) and JP6 (1-2).
Use an AC adapter of 5 to 6 [V] and 0.5A or more.
Use a plug with the internal diameter of 2.1mm, external diameter of 5.5mm, and the positive central polarity. Be aware of the polarity.

USB feed

Connect the jumper pins to JP4 (3-4) and JP6 (1-2).
Connect the USB-UART conversion cable supplied with the Evaluation and Development Kit to UART0 or UART1, and the USB terminal to your computer.

4 x AA batteries

Connect the jumper pins to JP4 (5-6) and JP6 (1-2). (Internal regulator is used)
*In this configuration, do not apply voltage equal to or exceeding 6.4V.
*006P dry cells cannot be used.
*Protect against reverse connection or short-circuit. The fuse (F2) blows in case of emergency to protect the circuit.

2 x AA batteries

Connecting the jumper pins JP4 (5-6) and JP6 (3-4) can directly connect dry cells for use. (Internal regulator is used)
*In this configuration, do not apply voltage equal to or exceeding 3.6V.
*006P dry cells cannot be used.
*Protect against reverse connection or short-circuit. The fuse (F2) blows in case of emergency to protect the circuit.

J6 (LCD Backlight)

The LCD backlight is lit by connecting J6 on the sensor node (with the LCD screen) of the ZigBee / IEEE802.15.4 Evaluation and Development Kit.

JP5 (Current Measurement Pin)

The pins to measure consumption current are mounted.

Pin 1-2 and Pin 3-4 are connected in parallel to the 100mΩ current sensing resistor.

To measure the current of the wireless engine only of the ZigBee/IEEE802.15.4 module, measure the current of Pin 3-4 and divide the value by 100mΩ.

To measure the current of the entire circuit, measure the current of Pin 1-2 and divide the value by 100mΩ. The current consumed by the regulator (IC1) and pilot lamp (D4) is not included.
