Balancing Circuit module for LiFePO4 cells - voltage 3.60V. Controlled resistance balancing module for limiting overcharge LiFePO4 cell (3.2V). Operating parameters: Border Balancing voltage: 3.60 V (+ / - 0.05V) [Detection Voltage] Balance voltage release: 3.50 V (+ / - 0.05V) [Release Voltage] Maximum voltage: Balancing Current: 0 ~ 1.7A Power consumption: Operating temperature: -40 to +125 °C Temperature of the resistors to 85 °C To get more power balancing, they can involved in parallel connection.

Descrição: Módulo novo e sem uso. DS3231 é um módulo I2C real-time clock (RTC), low-cost, muito preciso, com compensador de temperatura integrado eoscilador de cristal. Dispõe de suporte para bateria, pelo que desligando a energia ao módulo mantém-se a precisão e contagem de tempo. RTC maintains seconds, minutes, hours, day, date, month, and year information. Less than 31 days of the month, the end date will be automatically adjusted, including corrections for leap year. The clock operates in either the 24 hours or band / AM / PM indication of the 12-hour format. Provides two configurable alarm clock and a calendar can be set to a square wave output. Address and data are transferred serially through an I2C bidirectional bus. A precision temperature-compensated voltage reference and comparator circuit monitors the status of VCC to detect power failures, provide a reset output, and if necessary, automatically switch to the backup power supply. In addition, / RST pin is monitored as generating μP reset manually. O modulo dispõe de um sensor de temperatura, que pode ser lido também via I2C. Parâmetros: Dimesnsões: 38mm (comprimento) x 22mm (largura) x 14mm (altura) Peso: 8g Alimentação: de 3,3 a 5,5 V chip: high-precision clock chip DS3231 Precisão: 2 ppm, com erro de cerca de 1 minuto (0 a 40C). Calendar alarm clock with two programmable square wave output RTC (Real time clock) gerador de segundos, minutos, horas, dia do mês, dia da semana, mês e ano. O sensor de temperatura do chip tem uma precisão de +/- 3 C. Memória: AT24C32 (storage capacity 32K) Interface I2C, com velocidade máxima de transmissão (Vcc=5V) de 400KHz. Pode concantenar o espaço de memoria com outros bancos com a manipulação de endereços físicos A0/A1/A2. Endereço I2C é 0x57 Sem pilha A venda inclui apenas: 1* module (sem pilha) Entrego em mãos em Lisboa, ou envio por correio, à cobrança, com todas as despesas a cargo do comprador.

The sensor detection range can be through the potentiometer to adjust and have small interference, easy to assemble, easy to use, etc, can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on many occasions. Module Parameter: 1. When the module detects obstacles in front of the signal, the green indicator on the circuit board light level and at the same time the OUT port output low level signal, the detection module from 2 ~ 30cm, 35°detection Angle, test distance can be adjusted through the potentiometer, adjustable potentiometer clockwise, the detection distance increases; Counter-clockwise tuning potentiometer, detection distance is reduced. 2. Sensors, active infrared reflection detection, therefore the reflectivity and shape of the target is the key of the detection range. White one black detection range, minimum maximum; Small area of the object distance, large distance. 3. The sensor module output port OUT can be directly connected to the microcontroller IO port can, also can drive a 5v relay directly; Connection mode: the VCC - VCC; GND - GND; The OUT - the IO 4. The comparator USES the LM393, working stability; 5. Can be used for 3 to 5v dc power to power supply module. When power on, the red power indicator light lit; 6. 3 mm screw holes, easy fixed, installation; 7. Circuit board size: 3.2cm*1.4cm 8. Each module is shipped already compare threshold voltage through the potentiometer to adjust good, not special circumstances, please do not arbitrarily adjust the potentiometer. Module interface specification: 1. VCC voltage is 3.3V to 5V converter (which can be directly connected to 5V single-chip microcontroller and 3.3V) 2. GND external GND 3. OUT of small plate digital output interface (0 and 1) Package Included: 1 x Module
