Hi Ben,
Thanks for your answer.
The new TinyScreen+ board you mention sounds interesting.
Especially, the choice of a u-blox 8th generation GPS is fine because of the large reconfigurability, e.g. dynamic model, combination of GNSS constellations etc. Reconfiguration can be done by sending a series of ubx messages or preferably by using the nice environment of u-center, that translates those rather complex messages for the user.
It is therefore essential that the planned ZOE-M8B GPS will have the possibility for an off-line UART-USB connection to a PC with this u-center programme. It is also essential that the chosen configuration can be kept in internal GPS back-up memory for some time using a back-up battery.
The combination with LSM9DS1, BME280, and microSD slot provides a compact solution.
Assuming that the GPS antenna is not mounted on the board itself, this new TinyScreen+ board could be placed vertically in many model rockets even with small diameter, down to 35 mm. In case of horizontal position it can be applied with outside diameter down to 42 mm.
I am currently preparing the integration of a Mateksys M8Q-5883 GPS board, a 20 x 20 mm board with the u-blox SAM-M8Q GPS, which also includes the 15 x 15 GPS patch antenna. This is the smallest board with this M8Q-5883GPS I have found.
Connected through a Tiny Shield protoboard, the package with TinyZero, Combo Sensor TinyShield and MicroSD TinyShield will fit in a 35 mm diameter model rocket with the GPS antenna looking upwards.
