In default, UART2 (pin1 and pin2) are used for bypass communication and UART0(pin16 and pin17) are used for output of debugging information and burning firmware. Pleaserefer to the description in DC Characteristics for UART output current level.2. PDN is hardware reset for the module and will be effective with VIL. Configurationinformation will be remained after module reset. The module has pull-up process for PDNdesigned internally.3. In default, PIN13 (GPIO8) is the PIN for external LED indicator to show the moduleconfiguration status and output VIH after configuration is successful.4. In default, PIN14 (GPIO5) is the module software reset PIN and will be effective withVIH. The previous configuration information will be cleared after the module is reset (reset tofactory settings).5. The module supports max 4 channels of external interruption simultaneously exceptGPIO25 and UART0.6. The ADC is 10bit with input voltage 0-2V7. The power supply VDD should not be lower than 3.3V.4.3.

- 17 -This device complies with Part 15 of the FCC Rules. Operation is subject to thefollowing two conditions:(1) This device may not cause harmful interference, and(2) This device must accept any interference received, including interference thatmay cause undesired operation.Note: This product has been tested and found to comply with the limits for a ClassB digital device, pursuant to Part 15 of the FCC Rules. These limits are designed toprovide reasonable protection against harmful interference in a residentialinstallation. This product generates, uses, and can radiate radio frequency energyand, if not installed and used in accordance with the instructions, may causeharmful interference to radio communications. However, there is no guarantee thatinterference will not occur in a particular installation. If this product does causeharmful interference to radio or television reception, which can be determined byturning the equipment off and on, the user is encouraged to try to correct theinterference 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 thereceiver is connected.—Consult the dealer or an experienced radio/TV technician for help.Please take attention that changes or modification not expressly approved by theparty responsible for compliance could void the user’s authority to operate theequipment.This equipment should be installed and operated with a minimum distance 20cmbetween the radiator and your body

L'exploitation est autorisée aux deux conditionssuivantes :(1) l'appareil ne doit pas produire de brouillage, et(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi,même si le brouillage est susceptible d'en compromettre le fonctionnement.Under Industry Canada regulations, this radio transmitter may only operate using anantenna of a type and maximum (or lesser) gain approved for the transmitter byIndustry Canada. To reduce potential radio interference to other users, the antennatype and its gain should be so chosen that the equivalent isotropically radiated power(e.i.r.p.) is not more than that necessary for successful communication.Conformément à la réglementation d'Industrie Canada, le présent émetteur radiopeutfonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvépour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillageradioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne etson gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépassepas l'intensité nécessaire à l'établissement d'une communication satisfaisante.The module is limited to OEM installation ONLYThe OEM integrator is responsible for ensuring that the end-user has no manualinstruction to remove or install module.When the FCC identification number or ISED certification number is not visible whenthe module is installed inside another device, then the outside of the device intowhich the module is installed must also display a label referring to the enclosedmodule. This exterior label can use wording such as the following: “Contains FCC ID:or ”Contains IC: and the information shouldbe also contained in the devices’ user manual.2ACDZ-BL3335-P 23239-BL3335P
