 High Power LED Drive DC-2A-Max, Adjustable CC&CV

This is the LED drive module, constant CC and CV output (current and voltage), adjustable output, maximum output current  is at 2A, maybe not higher enough to drive the 100W LED, but for relevant smaller LED, for example 1W-5W, it’s good enough.

You can also build an lithium battery charger with it, just spread the idea.

20Pcs 5mm RGB Disciplinary Flashing LEDs

An LED flashing without MCU-control necessary, fast and slow flashing in turns, it’s very popular and interesting products, people build a lot of strange things with it. But we don’t know what it can exactly, where need a flashing LED.. maybe an night-light or decoration lamp? Anyway it’s a fun-to-have and strange product. See the video in the product description how it looks exactly.

DS1307 Time RTC Module I2C 1-Year-Lifetime

One of the best product this week I think, the RTC module with chargeable battery, EEPROM data-storage and 1 year lifetime without charging. The time is no a problem anymore, no worry about the battery, lose power or lose data, this module is all handled. One module to solve all these problems.

LM2596S-ADJ DC-DC Small-Tiny Adjustable Step-Down Module (3-40Vin, 1.5-35Vout)

We already have one step-down DC-DC module, now this is another one, using real LM2596-ADJ IC, but this is not the killing point on this module, the most important feature of it is the size, you can already see how compact it is from the picture, and we believe it’s the one of the smallest step-down DC-DC module on the world, maybe the only. And position holes and status LED is also included. For power details, feel free to read in product descritipion.
