May be it's help you - in my case with Winbond W25X40CL changing code in SPIFlash.h solve the problem with CRC error:

i change this:

#define SPIFLASH_BLOCKERASE_32K   0x52        //!< erase one 32K block of flash memory

on this:

#define SPIFLASH_BLOCKERASE_32K   0xD8        //!< erase one 64K block of flash memory

@yveaux Sorry, i don't test the range of nodes - plan to use in the 2 floor house of 60 meters.
But you opinion is correct, this design is compromise of size, pins count and range degradate.
This is prototype, work good about 1 year:

@feanor-anglin said in Newbie wants to do everything wired:

If you like it, please feel free to contact me. We've made some significant progress, which is not published yet.

I am also intresting in implementation of RS485 in my MySensors network, and i like yor hardware and use some of your ideas in my project Simple compact RS485 node (ATmega328 + MAX485) ,

As i see, two first module is impulse, but third - linear?

@dzjr This is terrible, but yesterday I received a message from PSBs.io that my order from 04/13/2020 is only sent ..

@dzjr I am ordered a new revision of this PCB at 2020.04.13, and the order status is "in fabrication" too, don't worry.

@dzjr I am using simple solder station like 936 with 900M-T-I iron tip, first solder the MCU and pin-headers, programm with USBASP using pads SCK, MISO, MOSI, RES, VCC ang GND, then solder other components (MAX485, resistors and capacitors).

@dzjr Ordering PCBs you will get only pcb, without components (no matter - SMD or TH). You may use PCB assebling service like JLCPCB or other, or you may solder SMD components yourself, it is not so hard, as you can think.

@dzjr I can upload new revision, but it still not tested in hardware, only ready to place order for PCB!

Soon a new revision of the board with the possibility of installing memory for OTA and fix some components footprints will be ready.

@VonJoost I see in serial console about the same picture - dump is 000000....

@sergio-rius sorry, my mistake, missed of using RFM69 in your setup..

@sergio-rius Pinout as described here Building an Ethernet Gateway, i am use module like this:

and my sketch on 20-Feb-2019 is:

#define MY_BAUD_RATE 9600
//#define MY_RF24_PA_LEVEL RF24_PA_MIN
#undef MY_REGISTRATION_FEATURE
#undef MY_CORE_COMPATIBILITY_CHECK

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

// When ENC28J60 is connected we have to move CE/CSN pins for NRF radio
#define MY_RF24_CE_PIN 5
#define MY_RF24_CS_PIN 6

// Enable gateway ethernet module type 
#define MY_GATEWAY_ENC28J60

// Gateway IP address
#define MY_IP_ADDRESS 192,168,1,235

// The port to keep open on node server mode / or port to contact in client mode
#define MY_PORT 5003   

// Controller ip address. Enables client mode (default is "server" mode). 
// Also enable this if MY_USE_UDP is used and you want sensor data sent somewhere. 
//#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 254   
 
// The MAC address can be anything you want but should be unique on your network.
// Newer boards have a MAC address printed on the underside of the PCB, which you can (optionally) use.
// Note that most of the Ardunio examples use  "DEAD BEEF FEED" for the MAC address.
#define MY_MAC_ADDRESS 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED

// Flash leds on rx/tx/err
//#define MY_LEDS_BLINKING_FEATURE

// Set blinking period
//#define MY_DEFAULT_LED_BLINK_PERIOD 300

// Enable inclusion mode
//#define MY_INCLUSION_MODE_FEATURE

// Enable Inclusion mode button on gateway
//#define MY_INCLUSION_BUTTON_FEATURE

// Set inclusion mode duration (in seconds)
//#define MY_INCLUSION_MODE_DURATION 60 

// Digital pin used for inclusion mode button
//#define MY_INCLUSION_MODE_BUTTON_PIN  3 

//#define MY_DEFAULT_ERR_LED_PIN 7  // Error led pin
