    Hi Andrew:
    Thanks for your advice, we believe that waterproof function is important in harsh environments for groves. But since the sensor itself needs to be waterproof, we believe that an enclosure for the whole grove module may be better.
    Please let us know your opinion.

    Perhaps the OPL Excel-file could have more columns like SMD/THT, Power, accuracy/tolerance, voltage

    I have been searching in the OPL Excel-list and I need some of the following components to be able to order soldered prototype.
    The well-known 555 timer, more Zener values (3, 4.7, 5, 6.2, 8.2, 10, 12, 15, 20 Volt) and perhaps some with more power 1W, al least one comparator (LM2903, LTC1716, LTC144x, LTC184x), voltage reference (LM4120, LM4132, LT10xx, LT66xx)
    FET should have low Rds(on) and if possible logic value gate threshold. But most important is low Rds(on) (CSD16570Q5B, CSD19506KCS and with dualcool csd16407q5c)
    And maybe some current sense IC like INA1x9.
    Perhaps a current sense resistor (LKV25R001FER)

    Of course it depends on what components are available for you and at what cost.
