With some exercise, this TQFP48 chip it can be soldered by yourself see here how to do it. You will, however, find out that the soldering is not so easy like in the examples.First up, we need a simple program to get the Python sending data over the serial port.

In order to make all SAMD21G pins available, we have to install the SAM 15x15 package. All we need is the SAMD21 with pre-programmed bootloader, a crystal and some capacitors: Note that the Arduino Zero board contains a lot of components however these are in principle not all necessary. This simplicity saves costs and board space. The SAMD21 instead, has a built-in serial interface which can directly be connected to an USB cable. The ATmega328 always needs an additional controller for programming. SAMD21 configuration Built in Serial interface These are the main characteristics of the J, G and E types: The ATSAMD21G18A-AUT is the 48 pin version with 256k byte flash memory: Note that we need a SAMD21G with a preprogrammed bootloader. You can buy the SAMD21G with bootloader HERE. SAMD21G with a preprogrammed bootloader for sale

*If the USB is not used, the 2 USB pins are also available, which increases the number of free pins to 36. Pins may have many other peripheral functions, but in order not to lose overview, these are not indicated with a letter in the schematic symbol: The most important pin peripheral functions are indicated with letters in the schematic symbol:ĭ = general purpose I/O, digitalWrite(), digitalRead() The Arduino Zero, which was released in 2015, contains the SAMD21G this is a fast processor with a TQFP48 package.Ĭomplete microcontroller development system with the Arduino SAMD21GĪs you can see, we hardly need extra components to build a complete microcontroller development system with the Arduino SAMD21G:Ĭomplete microcontroller development system with the Arduino SAMD21G Eagle libraryĭownload the SAMD21G Eagle library HERE for the Eagle schematic symbol of the image above. I have developed a sophisticated e-bike computer, called the E-bike cable killer it requires a small but powerful Arduino microcontroller. The widely used ATmega328, used at the Arduino Uno, doesn't have enough connections and is too slow the main advantage is that its dual inline package fits into a normal IC socket.īefore 2015, the only faster Arduino alternative was the Arduino Due, but the processor has 144 pins and that is too much of a good thing. Despite the small size, it has more I/O pins than the Arduino Zero: 34 instead of 20. The SAM 15x15 is an Arduino development board of just 15 x 15mm, with the same powerful controller as the Arduino Zero: the SAMD21G18. The smallest Arduino compatible ATSAMD21 board: 15x15 mm, 34 I/O pins That is why I will share my experience with the SAMD21 and discuss some particularities.Īrduino SAM-D21 with built in USB For sale: Mini Arduino compatible SAMD21 development board 15x15mm Since it is quite new, there is not so much information about it on the Internet. It is a 48MHz 32-bit ARM Cortex M0+ low power processor. Since 2015, there is a new powerful microcontroller available which can be programmed by the Arduino platform: the SAMD21.
