We do not have yet an example of PiEEG which is free from noise. We have suggested to use a Raspberry Pi zero w, eventually with a cable to reduce noise:
The Raspberry Pi RP2040 as shown in this device would be a good choice:
Or the successor model:
Raspberry Pi RP2040 has also 40 pins, but a different connector then the larger pi s. The wearable EEG system with an ADS1299 & a Raspberry Pi RP2040 is not open source. So the last option for PiEEG would be to solder a PiEEG shield to a Pi RP2040.
The Raspberry Pi RP2040 microcontroller chip was designed by Raspberry Pi in the United Kingdom
specifications:
• Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz
• 264KB of SRAM
• 4MB on-board Flash memory
• USB-C connector, keeps it up to date, easier to use
• Lithium battery recharge/discharge header, suitable for mobile devices
• Castellated module allows soldering direct to carrier boards
• USB 1.1 with device and host support
• Low-power sleep and dormant modes
• Drag-and-drop programming using mass storage over USB
• 26 × multi-function GPIO pins
• 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels
• Accurate clock and timer on-chip
• Temperature sensor
• 8 × Programmable I/O (PIO) state machines for custom peripheral support https://www.pi-shop.ch/rp2040-plus-based-on-raspberry-pi-mcu-rp2040
- Over the usb-c mutliple Raspberry Pi RP2040 board could in principle be connected to each other.
Information for product sellers who do stock market speculation and scalping with products mentioned by Peter Gamma on www.petergamma.org

According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and scalping with those, you will loose Peter Gamma from www.petergamma.org as a buyer of these products and as a reviewer. Is this not risky? Will you not loose a majority of your costumers as well?
And is it not so, that society in general does not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and scalping with these products?
And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and scalping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country.
And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and scalping with the products which are mentioned on www.petergamma.org. And if they do not have yet the legal basis there to do so, he will fight for it.
What is a scalping?
Scalping is a trading strategy in which an investor buys and sells a single asset multiple times throughout the day. The goal of a scalper is to make a small profit over a large number of small trades, rather than a huge profit on each individual trade.
What is a scalper?
A scalper is someone who buys something and resells it at a price far above the initial cost. For instance some says: “He got theater tickets through a scalper”: Someone who buys tickets to an event in order to resell them at a profit. And is it not also scalping if you take reviews from this site to make out of it a new product offer, and sell it for a higher price? We doubt that you will be successful with it. Since Peter Gamma will review your product and will user not come back to www.petergamma.org after that?
