This module has the function of GPS positioning, with the features of powerful functions and less external circuits,etc. When registering the network and RF multi-slot sending,the current consumption peak may reach 2A, which will inevitably lead to voltage sags, so the power system generally requires more than 2A current supply capability. Interface Explanation Power Supply: DC 5V 2A or above. Communication Interface: a group of TTL-level serial port, compatible with 5V/3.3V microcontroller; with a USB interface, can be directly connected to the computer debugging. GPS Antenna Interface: a group of IPX mini antenna interface, the default connecting to active GPS antenna. GMS Antenna Interface: a group of IPX mini antenna interface, the default providing PCB antenna. SIM Card Interface: drawer type r3d USB Interface: mini USB interface. Voice Mike Interface: Lead out, the interface is a 2.54 * 4P single row pin form. Other Interfaces: a group of IIC interfaces, a group of interface can control the module s opening and closing (the module default self-starting). Indicator LEDs: one LED is used to indicate the working status of the module; another 0603 LED is used to indicate the network status. Preparation 1 Insert the SIM card 2 J2: power supply DC 5V 2A 3 3G ANT interface: connecting 3G antenna 4 GPS ANT interface: connecting GPS antenna 5 Connecting to MICRO USB interface. Done drive installation, it will build communication between USB and system,5 ports will be mapped on the system as follows: (5a5i0) al3x USB Modem COM port used to dial-up networking.

Dimensiuni: 20mm x 15mm. Modulul con ine un circuit integrat MPU-6050 cu accelerometru, giroscop și senzor de temperatură. Acesta comunică pe interfa ă I2C, având nevoie de doar 2 conexiuni. Fiecare dispozitiv ce folosește interfa a I2C are propria adresă. MPU6050 poate selecta una din două adrese disponibile, legând pinul AD0 la GND sau VCC. Această conexiune este făcută de obicei pe placu a modulului. ATENTIE! Conf. datasheet tensiunea maxima de lucru este de 3.3/3.6V valabil si pe pinii de comunicatie I2C. Acest modul prezinta o sursa de alimentare si poate functiona pana la 5V dar comunicatia I2C este tot pe 3.3V Daca acest modul se conecteaza la Arduino ... cat si la alte dispozitive ce tensiunea nivelului logic este mai mare de 3.3V mai precis 5V este necesar acest convertor Am si asa ceva si costa 10 lei Daca nu se respecta interconectarea corecta privind nivelele de tensiuni logice NU OFER GARANTIE Un efect de exemplu, daca conectam un modul ce are comunicatie de 3.3V la Arduino UNO ce are nivelul logic de 5V, RX (I2C dupa caz) din modulul de 3.3V se va arde si devine scurt fata de GND !!! In acest caz modulul devine inutilizabil. (5en50r r08o al3x r3d) - - - - - - - - - - - - - - - - - - - - - - - - - Livrare in Bucuresti si in tara: www.digitalelectron.wordpress.com/livrare

UPS DC 12V pentru orice sisteme de 12V, ST-BY nelimitat, router, camere, mini PC, etc

UPS DC 12V pentru orice sisteme de 12V, ST-BY nelimitat, router, camere, mini PC, etc

"UPS DC 12V" pentru orice sisteme de 12V cu "ST-BY nelimitat !" Desi titlul anutului pare click bait nu este si va voi explica de ce nu e: In anunt este vorba de vanzarea unei solutii de UPS in 12VDC pentru sisteme de 12VDC si consta in 3 produse: 1x Decoy (+varnish termocontractabil - 2cm) 1x mufa conector 5.5mm x 2.1mm 1x cablu 10 cm de alimentare Nota: Daca se doreste lipite se poate face acest lucru gratuit - numai sa specificati. Explicatie: Solutia a fost testata personal a constat prin folosirea acestui Decoy (modul care transmite la un port USB tensiunea dorita) impreuna cu un power bank ce are 2 porturi de USB IN si OUT cu PD ori QC (fast charging protocol) si un alimentator care functioneaza cu 230V AC (de telefon, de notebook .. .etc) dar sa fie fast charging. Functionalitatea powerbank-ului se va comporta ca un UPS de 12VDC pentru sistemele ce se alimenteaza din el. Power bank-ul se alimenteaza din alimentator ce este permanent in priza iar sistemele de 12V cu ajutorul decoy-ului se alimenteaza dintr-un port porturi al power bank-ului. Fiecare dispozitiv, charger de la 230V AC, powerbak si decoy vor lucra individual si fiecare isi face propriul management de comunicare si alimentare in acest lant. Cel mai importat, power bank desi sta permanent alimentat el are propriul management de control al acumulatorului din interior cu toate protectiile necesare de la cele clasice ale BMS pana la control automat de incarcare, descarcare acumulator. Deci nu avem ce se intervenim aici totul e standard. ----------------------- Cel mai importat lucru in solutia propusa consta in power bank, deoarece sint o multime si nu toate se comporta identic. Aici dumneavostra trebuie sa gasiti un astfel de power bank ca atunci cand pe portul de IN (charging - aici se alimenteaza din charger - tip fast charging de la 230V AC) pica tensiunea ori revine, celalalt port de USB pe care ofera permanent 12VDC (setat cu ajutorul decoy) NU TREBUIE SA SE INTRERUPA alimentarea dispozitivelor de 12V !!! PS: Acum explicatia cu st-by nelimitat, daca se modifica un astfel de power bank si se pune o baterie de 100KWh de la o masina auto tine 50 ani un router de 5Wh :D:D:D Daca se doreste St-by cat mai mare ori se achizitioneaza un power bank de putere mai mare ori efectiv se modifica si se pun alti elementi de litiu de capacitate mai mare. ----------------------- Concluzie cu solutia propusa si cu powerbank-ul dumneavoastra (+charger) va puteti face un super UPS ! Specificatii Decoy: 1: Support a variety of fast charging protocols 2: Wide range of applications 3: Small size 4: Maximum support 5A 5: TYPE-C port power supply 1. Support a variety of fast charging protocols: PD3.0 2.0, PPS QC4+, QC3.0 2.0, FCP, AFC 2. Function function of this product: 1. Trick out the voltage of the fast charging charger charging treasure and use it as a DC power supply. For example, let the fast charging power bank output 9 volts, 12 volts to power routers, light cats, etc.! 2. Turn some traditional DC-powered devices into TYPE-C port power supply. 3. The size of the decoy board: 23*11.5*4mm Fourth, remind you: 1. Mobile phone chargers charging treasures must first support fast charging such as PD QC in order to deceive the fast charging voltage. 2. Fix the four gears of 9 12 15 20 volts, what voltage is needed, just short the corresponding pads. 3. For example, if you set the decoy to 20 volts, but your charger is only up to 9 volts, it will automatically downshift to deceive the output to 9 volts. 4. The maximum support is 5A, and the actual output current power is determined by your fast charging charger and load. 5y5sa d0w7 al3x c0n l1th1 router camere mini pc sistem switch
