Sodium Persulfate B327 (PCB) Printed Circuit Board Etching 1kg features:
A compound for etching of printed circuit boards and pickling of copper. An ideal alternative to ferric chloride. It is readily soluble and does not crystallize from the solution. It etches evenly, ensures the sharpness of contours and minimizes undercutting. Usage: Dissolve the preparation in 0.5 l of water at a temperature of 50°C. Perform etching at 40°C (max. 50°C). Bath movement ensures quicker etching. The etching solution must not be stored in hermetically sealed containers due to the risk of developing overpressure and cracks.

Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and you have your own on the digispark wiki. Arduino compatible Attiny85 Digispark board features:
- USB power supply
- External power supply (7v-35v DC 12v maximum recommended)
- 5V DC 500mA regulator on board
- Programmable with the Arduino IDE
- Loaded with Micronucleus bootloader
