Placa Soldada
Guia de montagem da placa MCC25
A placa foi projetada para facilitar a montagem, mas é necessário tomar alguns cuidados devido a algumas alterações no projeto.
Passo a Passo
| Passo | Instruções | Imagem |
|---|---|---|
| 1 | Realizar a troca do resistor R20 de 15Ω para um resistor de 4.7Ω. |  |
| 2 | Isolar o pino de referência do sensor de efeito HALL "U2" raspando as trilhas conectadas ao GND, em ambos os lados da placa.( Somente raspar as trilhas relacionadas ao pino de referência, o resto manter igual ) |  |
| 3 | Não realizar a solda do resistor R7, pois ele será soldado em outro local da placa. |  |
| 4 | Após isolar o pino de referência do sensor de efeito HALL, realizar a solda dele normalmente. Em seguida, soldar um resistor de 150Ω entre o pino de referência e o output do sensor. (Certificar-se de que não há curto-circuito). |  |
| 5 | Montagem do snubber: verificar a necessidade, mas a dica de montagem é usar um diodo TVS Schottky 100V, capacitor de 4.7nF 100V e resistor 4.7KΩ 3W. |  |
