2. Hardware Design
All unused pins should be left floating; do not ground.
All GND pins must be well grounded.
Traces should not be routed underneath the module.
2.1. Module Reflow Installation
The ART6212 is a surface mount Bluetooth module supplied on a 44 pin, 6-layer PCB. The final assembly
recommended reflow profiles are:
For RoHS/Pb-free applications, Sn96.5/Ag3.0/Cu0.5 solder is recommended.
Maximum peak temperature of 230° - 240°C (below 250°C).
Maximum rise and fall slope after liquidous of < 2°C/second.
Maximum rise and fall slope after liquidous of < 3°C/second.
Maximum time at liquidous of 40 – 80 seconds.

Note: It is better to use 9pF 26MHz crystal (Y1). The load capacitors (C17, C18) of crystal circuit is
recommended to be 12pF or 15pF which is depended the design of the PCB layout traces. The capacitors
ESR is better to be 0.1ohm at 100MHz. The traces from the crystal to the ART6212-T pads should be as
short as possible.

The recommended 26MHz crystal PN is Q22FA1280002000 and it’s soldered at the user’s PCB board by
the following condition:
4. Startup behavior
4.1. WL_REG_ON & BT_RST_N
These pins are always an input pins, active low, with a PD during reset. This signal MUST be active during
power supplies initialization and, when all power supplies are stable, it must remain active low for at least 2
cycles of the slow clock in order to insure good reset functionality.
When WL_REG_ON is low, the WIFI chip is power down.
When BT_RST_N is low, the WIFI chip is power down.
4.2. UART and SPI interface
UART_CTS is an input with PU, UART_RXD is an input with PU, UART_TXD toggles from input PU to output
High and UART_RTS toggles from input PU to output Low 70ms after reset, enabling UART communication
if needed.

7. Warning
Please note that changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
—Consult the dealer or an experienced radio/TV technician for help.
This equipment complies with radio frequency exposure limits set forth by the FCC for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20 cm between the device and the user or
bystanders.
This device must not be co-located or operating in conjunction with any other antenna or transmitter.
The user (OEM) must follow the datasheet instruction and Hardware guide. It is better to use the datasheet part3 reference
design.
The OEM
integrator must make the label (containing
ID X3ZWFMOD1) can
FCC
be seen by the operator.
