ESP-01s 1 MB WiFi Microcontroller ESP8266 ESP01s Replace ESP-01 ESP01

 

ESP-01s 1 MB WiFi Microcontroller ESP8266 ESP01s Replace ESP-01 ESP01 - Here comes ESP-01s, the new version of the well-known ESP-01.

ESP-01s vs ESP-01 differences:
1. Red power LED is removed (saving a couple mA and good for battery operated project)
2. Blue LED is now on pin 2
3. Has silkscreen with pin labeling on the back
4. Has far more chip capacitors for better working stability
5. The WiFi range has been slightly increased
6. Has a pull-up resistor connected between CH_PD and Vcc, so only need to connect Vcc & Gnd for booting and running

NodeMCU v2 Amica ESP8266 CP2102 4MB WiFi Microcontroller ESP-12E ESP12

NodeMCU v2 Amica ESP8266 CP2102 4MB WiFi Microcontroller ESP-12E ESP12 - This module is an ideal version, still using the yellow Tantalum Capacitor (vs the black color which is inferior) and more premium components. 
It will be more stable when used in the Lab or in the field. (See picture no.3)
It's not the CHEAPER NodeMCU v3 as it's bigger and uses the inferior USB Chip, the CH340.
Facts about v3:
1. Not a continuation of NodeMCU v2 and produced by a different manufacturer
2. Bigger size (58 x 31mm) than v2 (48 x 26mm)
3. Not breadboard-friendly, v3 will fill the entire breadboard pin, so it can't be used to connect other peripherals.

IC CPU Z80 ZILOG

 

Zilog, Inc., formerly known as Zilog (which stands for "Z (last word in) unified logic"), is an American manufacturer of 8-bit and 16-bit microcontrollers, and is best known for the Intel 8080-compatible Z80 series.
Zilog was founded in California in 1974 by Federico Faggin, who left Intel after working on the 4004 and 8080 microprocessors. The company became a subsidiary of Exxon in 1980, but management and employees bought it back in 1989 led by Dr Edgar Sack.
Z80(i) is an enhanced implementation of the Intel 8080 architecture, which is faster, more capable, and significantly cheaper; along with the 6502 it is one of the most popular 8-bit processors for general purpose microcomputers and other applications. It was used in the Nintendo Game Boy, Sinclair ZX80, ZX81, ZX Spectrum and Amstrad CPC home computers as well as the MSX architecture and the Microbee and Tandy TRS-80 series—among many others. More than just sparking improvements in the budding fields of home computing and gaming, the Z-80 also sparked a revolution in electronic music, as the first truly polyphonic programmable synthesizers (as well as their peripherals) relied heavily on the implementation of these CPUs.
