The Minipro TL866 is very popular among hobbyist because of its low price and ease of use. Its list of supported chips is however somewhat limited compared to more expensive professional programmers. The E2R16 adapter adds support for the ROM pinout compatible EPROM of the 27C400 series which are compatible with Amiga computers and many arcade machines.
The GGLABS A520HD is the HDTV equivalent of the classic Commodore A520 TV modulator. Instead of encoding the Amiga video signal to a low quality composite output it converts the RGB output to a high quality YPbPr signal compatible with HDTVs with a component input. The A520HD connects to the Amiga 23-pin video port and is powered directly from the system.
Both the commodore 64 and the 128 have a software UART implementation that limits the useful speed to 2400 bauds. To work around this limitation Dr. Evil Labs and later CMD produced the SwiftLink232 and Turbo232 cartridges based on the 6551 ACIA chip. Both of these have been out of production for a very long time. GLINK232 is a modern replacement for the swiftlink232 allowing the commodore 64/128 to communicate at speeds up to 38400 bauds.
High power LEDs require a constant current power supply for optimal operation. GLED1 is designed to drive 10W white LEDs (9 diodes in series) from a 12V or 24V supply. The board can be used down to 3V but the maximum output power will be reduced in this case. The design supports discrete level dimming using a two or three way switch or continuous control using a PWM signal. The design is based on the ON Semiconductor NCP3065/3066.
Many MCU applications use electro-mechanical relays to control AC loads. While this is an excellent solution for occasionally turning on/off a load it is not suited for frequent switching or PWM applications. SSR01 is an opto-coupled solid state relay that can control two AC loads up to 16A each.
USTK01 is a small USB device that allows the connection of thermocouples (using MAX6675 or MAX 31855), humidity sensors (DHT11/DHT22) or any I2C or RS232 device (5V or 3.3V).
Despite the significant advantages in size, weight and efficiency, switching AC-DC supplies are not very common with hobbyist due to their complexity and scarcity of ready to build kits.
PWR01 is a low power (~6W) universal voltage (100-240V) isolated AC-DC flyback converter based on the ST Microelectronics VIPer17. Either 5V or 12V output can be obtained using an off the shelf transformer.
Linear regulators from the 7800 series are often the choice for electronics hobbyists because of their ease of use, versatility, robustness and availability. G78xxHE is a very small DC-DC converter aimed to be a "drop in" replacement for the 7800 series regulators in TO-220 package. Thanks to its high efficiency the G78xxHE does not need to be connected to an heatsink even when delivering the maximum rated 7800 series current (1A) with large Vin-Vout deltas.
The Maxim MAX6675 and the newer MAX31855 thermocouple to SPI interface chips are very popular with electronics enthusiasts because of their extreme ease of use combined with good accuracy.
Both devices however are only available in SMD package making breadboard prototyping very difficult without using a suitable breakout PCB. Standard thermocouple connectors are also not breadboard friendly further aggravating the issue.
