Color: as picture shown

 IMPRESSIONS:

The hooks seems to be very good quality and very sharp, the plastic looks kinda cheap type, overall seems to be good anyway.

!!! ATTENTION !!!

The color is sent at random, i bought 3 of them and are all of green type.

 IMPRESSIONS:

The hooks seems to be very good quality and very sharp, the plastic looks good.

!!! ATTENTION !!!

On the image there are 5 items but on the Buy section there are 4 items #1 #2 #3 #5. I got the #5 and it is 50mm long x 5 grams not 40mm x 4.5 grams.

ITEM #5 is 50 mm.
I rotated the label with a program because was upside down.

BangGood.com - ATmega328P Nano V3 Controller Board Compatible Arduino Improved Version [SKU157951]


Arduino nano clone.


You can see/buy it here: >> LINK <<


UPDATE:
I can make a simple scheme that can be used to test all the pins (digital I/O, PWM, analog IN), if someone is interested just leave a comment below.

Specifications:
  • Microcontroller Atmel ATmega328
  • Operating Voltage (logic level): 5V
  • Input Voltage (recommended): 7V ~ 12V
  • Input Voltage (limits): 6V ~ 20 V
  • Digital I/O Pins: 14 (of which 6 provide PWM output)
  • Analog Input Pins: 8
  • Current per I/O Pin: 40mA (max) 20mA (recommended)
  • Flash Memory: 32KB (ATmega328) (of which 2 KB used by bootloader)
  • SRAM: 2KB (ATmega328)
  • EEPROM: 1KB (ATmega328)
  • Clock Speed: 16MHz

Antistatic package.The image is huge, open it in another tab !

This module price is (currently) 3.27$ (around 3€).
The soldering quality is high, i can't see any defect.
The ATMEGA is an ATmega328P, the voltage regulator is a AMS1117 and the USB/SERIAL converter is a CH340G. The four leds are all RED.
I recommend to download the datasheet and the pinout pdf for more info.

WARNING!
I can't find how much the CH340G can output on the 3.3v, with google i've found two values, 50 mA and 120mA, to stay safe i suggest to not go more than 50 mA.
I asked directly to BangGood, the CH340G can supply max 50 mA on the 3.3v, don't exceed this limit !

BangGood.com - 3A LM2577 DC-DC 50KHz Adjustable Step-up Power Converter Module [SKU072366]


Well, i got this some time ago but i used it 3 days ago, and... The horror.
Let's see why.

On the item page >> LINK << there are the info with some photos:

Specs and package infos.
Module photo on the page.


As you can see it say PACKAGE 1x LM2577 with INPUT 3..30v and OUTPUT 4..35v

But what i got instead ?
I got a module with an XL6009 indead of LM2577, i was thinking maybe is the same thing made by another manufacter but no. In the datasheet of the XL6009 (version 1.1 page 5) there is INPUT 5..32v and the OUTPUT can go up to 60v

But it don't end here, pics of my module:

The module i got.
  1. The 220uf 35v (*) input cap is twisted and soldered only on the negative pin !!!
  2. The output cap is only 50v but the output voltage can go up to 60v !!! The cap can explode !!!



How the hell this thing has passed the QC ?

(*) 220V is the code for :
      220 = uf
      V = 35v

trnd e Braun

Mi è arrivato un coupon da trnd per il progetto sul Braun WaterFlex :D

Spero di essere scelto perchè a quanto pare è perfetto sulle pelli sensibili (quando uso il rasoio divento viola >_>') ed è IPX7 quindi perfettamente stagno e utilizzabile durante la doccia (e io ci sto minimo un'ora).
Vedremo nei prossimi giorni >.</

Windows Developer Program for IoT - 2°



 Mi è arrivata una mail ma a quanto pare hanno già spedito tutte le schede ad alcuni fortunati >_<
Aimè non sono stato scelto U_U'''
Vabbè continuerò ad usare l'arduino collegato al nettop...
