quality, solid, construction; clearly oriented to developers
For DIP-40 Arduino compatible development board
Overall:
quality, solid, construction
clearly oriented to developers
Benefits:
A. MCU is socketed allowing easy replacement; so (a) can be used to re-program MCU IC's and then relocate them to another target board, (b) once the MCU is corrupted it may be easily replaced, (c) different AVR ATmega DIP40 MCU may be used (in my case used ATmega1284P).
B. Beyong ISP has also JTAG header connection, allowing professional debugging, subject to debugger device availability (in my case used Atmel-ICE device).
C. Has switchable 3.3 and 5V selection
D. Is already equipped with external 16MHz crystal (no need for upgrade)
E. The GND and Vcc pins are accessible via separate multiple pin headers allowing the developer to connect more than one jumper wires (typically required in projects)
F. The pins allow connectivity with both female and male jumper wires. Very convenient, accelerating development process.
G. On board annotations are rich (every single component and pin is annotated) and easily readable without ambiguities (almost, there is no need to resort to the schematic diagram)
H. The on board diagnostic LEDs allow the developer to observe all basic signals, as PWR, diagnostic-LED, Rx and Tx.
I. There is an on-board trimmer, to allow easy/direct development of "adjustable" funcionality (e.g. externally adjust a program value based on ADC port input)
Congratulations to the board designer.
