GatePi 4- Channel Relay with LoRa Module based on RP2040 GatePi is a low-power consumption data transmission board, comes with an onboard CH340 USB TO UART converter, Voltage Level Translator(74HC125V),E22-400T22S/E22-900T22S SMA antenna connector that covers 433/868/915 MHz frequency band, 4-Ch
Raspberry Pi RP2040 MCU or an ESP-12E WiFi module, with variations named RoundyPi and RoundyFi, respectively
The RP2040 StackyPi is a Pi Zero-sized Raspberry Pi that supports Raspberry Pi HATs. Acts like a RP2040, yet looks like a Zero.
RAIN RFID technology | Supports EPC Gen2V2 | ISO 18000-63 standard | M6E-Nano | Up to 200 Tags/Sec | ARM based Cortex-M4 architecture
StackyPi is a small and powerful board that has the RP2040 microcontroller and one set of 2x20 pin headers for connecting Raspberry Pi HATs. It implies that a Raspberry Pi HAT may be plugged in and operated on the StackyPi, allowing the user to execute additional operations.
