Revision History Revision number Revision date Summary of changes Authors 1.0 12/12/2022 Initial version D. Trimarchi FCC Warning Statement Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that may cause undesired operation. RF Exposure Statement To maintain compliance with FCCs RF Exposure guidelines, this equipment should be installed and operated with minimum distance of 20cm the radiator your body. This device and its antenna(s) must not be co-located or operation in conjunction with any other antenna or transmitter.

This Arduino Uno-compatible module has integrated Wi-Fi and has been designed to be the replacement of the Arduino UNOs ATmega328P. It can be used as a replacement of the ATmega328P (as shown in the pictures below) or as a stand-alone module, placed on a breadboard or soldered in a new board. The reference markets/application areas are: prototyping, makers, IoT Example of how to use Jolly Module with ad Arduino UNO. 1) Take an Arduino UNO 2) Remove the ATmega328P 3) Replace it with the Jolly module For more info, please visit: Jolly DEV (jolly-dev.com) 4 Copyright 2022 METECA SA.

Jolly module User Manual 5. Schematic 6 Copyright 2022 METECA SA. All rights reserved. Jolly module User Manual 6. Software Since the Jolly module has been designed to replace the ATMega328P of the Arduino UNO, it allows us to preserve the full compatibility of the pinout, firmware, and hardware architecture of its predecessor. Therefore, a secondary microcontroller was inserted to allow the addition of Wi-Fi functionality, the ESP8285. The two microcontrollers are connected to each other through two digital interfaces as can be seen from the schematic in the previous section: one SPI and one UART. In particular, the SPI interface which is the same exposed on the pinout of the module is used for data exchange, while the UART, is mainly used for programming the ESP8285 and for communication/programming of the ATMega328PB. The ESP8285 serial interface is active only during the programming phase so as not to interfere with the normal operation of the serial on ATMega328PB. The programming of the Wi-Fi chip is possible thanks to the presence of a boot key and a special firmware in the ATMega328PB. To have the whole module working properly, a custom Arduino Core has been designed for both the MCUs:

The Jolly AVR platform (tech-jollydev/jolly-arduino-platform (github.com)) The Jolly ESP platform (tech-jollydev/jolly-arduino-esp8285-platform (github.com)) NOTE: to ensure a proper working of both the platforms, the Arduino IDE version 1.8.13 or higher is strongly recommended. Platforms Installation To install the Jolly AVR platform in the Arduino IDE it is necessary to follow the following steps:

select the Preferences tab in the file menu add the following links to the Additional Boards Manager URLs:

https://tech-jollydev.github.io/package_jolly_index.json https://espressif.github.io/arduino-esp32/package_esp32_index.json https://arduino.esp8266.com/stable/package_esp8266com_index.json select the board menu in the tools menu and finally select the boards manager option by typing jolly in the search bar, the Jolly AVR Boards platform and the Jolly advanced platform should appear now the platforms can be installed Update the ESP8285 firmware A pre-compiled version of the default ESP8285 firmware is available under the path /firmwares/jolly_esp/ . The firmware is composed by two files: WiFiManager.bin and WiFiManager_spiff.bin. In case the firmware needs to be updated for any reason, there is a specific semi-automatic procedure to follow:

in Arduino IDE select the tools menu choose ESP8285 for the bootloader option as shown in the picture below 7 Copyright 2022 METECA SA. All rights reserved. Jolly module User Manual

press the boot button located on the Jolly module. While holding it pressed, press the reset button on the Arduino UNO for 1 second, then release it. Keep holding the boot button for 1 second longer, then release it Now the Jolly is entered in the boot mode for the ESP8285

finally click on burn bootloader option and the procedure will start automatically HINT: to keep track of the update process, enable both the compilation and upload radio button in the show verbose output during: option located in the file menu Preferences tab of the Arduino IDE To fully customize the code running on ESP8285 the dedicated platform must be used. To trigger the firmware update, the process is the same as depicted before: press the boot button located on the Jolly module; while holding it pressed, press the reset button on the Arduino UNO for 1 second, then release it. Keep holding the boot button for 1 second longer, then release it. Now Jolly module is in boot mode and a new firmware can be uploaded. 8 Copyright 2022 METECA SA. All rights reserved.
