LUCKY Portable Wireless Fish Finder for Shore Fishing

Product Information

I tried to connect to the microcontroller with a serial device on the soldering pad. They are connected to RX / TX of the microcontroller, V+ and gnd. But I was not able to see or trigger any data transfer event. I used realterm and a rs232 cable "spy". Rx or tx was not blinking or doing anything. One reason for its multi-functioning capacity is the portable and compact size of the gadget. It is small enough to fit even in the hand of a petite female, which means you could easily accompany it on a kayak or a small watercraft without it overcrowding your little vessel.

The display is another distinguishing part of this little guy. 2.8” LCD is better than other portable fish finders not only because of the size but also because of the quality of the view. Those are The IF amplifier input pin and IF amplifer bypass pin. (see picture of the typical schematic from the IC datasheet). After seeing the power of its sonar, I can finally understand why the company calls it one of the best castable fish finders. The puny size of the device has no impact on its sonar potential. The screen contains three colour tone adjustments along with tinkering options for fish icons. Meaning, you can fine-tune the unit to make it more responsive to the planned fishing type. Alluding to my earlier comment about wires and space, the unit has wired and wireless modes to let it adapt to the kind of fishing scenario you have in mind. If you have the force to throw it 147ft far, things will run without any glitch.Also need demodulation to remove any AC noise out of the transducer signal and convert to DC. Like a high pass low pass audio filter + DC conversion? x AA battery box with switch (This is added by ourselves as we think its the best way to power the signal box!) The AA32416 IC (on the right corner) is were I choose to invest time for now: I figure out all the IC pin connection and this is were I need your help to go further. I finded time to look into the circuit in more details. It is too big to be ruled in one post... I would like to share were I am now before I go further. your input will help understanding the next step.

built-in 5000mah battery]-this visual fish finder has a built-in 5000mah rechargeable battery, which can be used continuously for 5-8 hours when fully charged; it can also be charged with a power bank, which is convenient for outdoor use;Of the 16 pins, only 7 are connected and strange enough, pin 9 (IC final output pin is not connected - or I failed to find the link yet). I was expecting a lot from this pin.... (: What this IC do with only 7 pins? Can someone figure this out with my finding below? device for GPS, Fishfinder, Echosounder, Compass and battery indication and all displayed in a color screen!

Furthermore, you can also switch to wired mode to make it compatible with your chosen fishing type. Depth Capability Somewhere in the process, a timer is needed to control time between pulse and echo. Or the transducer frequency already integrate the time? Despite being small enough to fit in your hand, the unit has powerful sonar that can sink to an astonishing 328ft depth to collect information that will help you outwit the finned prey. Pin 12 (RSSI output pin) is connected to ground through a parallel arrangment of a 18 pf capacitor and a 1M resistor and it is the only pin that is connected to the microcontroller (pin 1).You can also take help from its shrill alarm to instantly know about the presence of fish in your vicinity. This feature tilts the balance in your favour during nighttime fishing and ice fishing. LCD Display This has a built in compass which tells you which direction and speed your boat is sailing and the distance to the marker and the home point. This is incredibly helpful for night fishing!
